Field Telescope – the real deal

You may have read a post I wrote ages ago about an inexpensive Indian-made “training” telescope? Well, here’s the real deal. A while back I was lucky enough to acquire a very nice 1917-vintage old-timey brass military telescope to use alongside my 1900-ish deer stalker’s telescope, and of course the half-sized, Indian-made “decorative” telescope.

Here’s a tip if you’re ever looking at one of these old telescopes online or at a second hand store with a view to buying it – If the seller says it must be broken because it won’t focus, then you’re probably very close to getting yourself a bargain. Why is that? These multiple draw telescopes won’t focus if you just twist the eyepiece. In fact, if you do that with this particular model, the eyepiece will unscrew and fall off! Nope, to focus these you must push in or pull out the last draw tube until the image comes into focus.

Now that we’ve gotten that out of the way, on to my telescope. The telescope is a World War One era British signalling  and general service telescope. It was used by signallers before radio communications became commonplace. Flashing electric light or signal mirror Morse code or perhaps semaphore flags were used to send messages over long distances and the message was received by an observer with a telescope.

Probably more famously, these were used by British and Commonwealth snipers in the First World War and while they were replaced in British service by a lighter model, this particular model of telescope soldiered on with Australian reconnaissance parties, intelligence officers and snipers during the Second World War too. In fact, I can’t lay my hand on the photo, but I’m pretty sure there’s a picture of an Aussie sniper spotter using one of these obsolete telescopes during the Korean War of the 1950s.

Simply captioned “Snipers 5th L.H., one firing and other pointing with telescope.”, I believe that this image shows famous Australian Light Horse sniper Billy Sing and one of his two main spotters, “Jack” Idriess on Gallipoli in 1915. The spotter here is seen using one of the telescopes in question which has been camouflaged with hessian strips. Idriess of course would later become well known as the author Ion L. Idriess.

The telescope is marked with the following –

The Low Power eyepiece is shown above its leather pouch. With a relatively narrow field of view, sometimes it’s easier to use the telescope with this lower power 20x eyepiece fitted.

As far as I can tell, it’s a variable 20x to 40x telescope with a brass body and has a leather covering on the barrel and the extending sun shade. It has two leather end caps, a shoulder strap and a small tubular leather pouch threaded onto the shoulder strap which holds the low or high power eyepiece – whichever isn’t fitted to the telescope at the time.

The telescope extended. It’s over a metre long and in fantastic condition for a 100 year old piece of equipment.

I bought it online from overseas with very little info from the seller. The pictures supplied by the seller were promising, with the 100 year old leather components looking almost pristine. I figured that if the leatherwork was in such great condition, then the rest of the telescope would be too. Sure, there was a risk that the objective lens may have been infested with fungus or smashed, but it was worth the risk and I was not disappointed. It’s a truly beautiful instrument.

If you look closely you can see the markings.

The weight was a huge surprise to me. I’ve taken the telescope along on several overnight bushwalking and swagwalking trips and you definitely notice the extra weight of the telescope and tripod.

The telescope is carried by the shoulder strap. The tripod seen here is not original to this telescope, it’s actually a few decades older and was originally a deer stalker’s or target shooter’s tripod since it came with a rifle rest attachment as well. When strapped up in this fashion, the tripod can also be carried on the telescope’s shoulder strap.

I’ve been using it for field panorama sketching and it really helps with the details. You could use binoculars for this purpose, but I think that to get the same sort of powerful magnification as with this telescope, the binos would be huge and prohibitively heavy for this sort of work.

When all closed up with both leather end caps fitted the telescope is very well protected and quite compact. Still very heavy though!

This is a powerful telescope – really powerful. Last full moon I set it up in the backyard to check out the moon. The image was spectacular. Clearly defined raters and debris trails from the meteor impacts. Due to full time auto focus on my phone’s camera I unfortunately I haven’t yet worked out how to take a photo through the telescope, but when I do I’ll take a whole lot and post them. It has to be seen to be believed.

The Hootchie – Part 1 – An Adventure Through Time – ADDENDUM

Back in the olden days, at the very dawn of this little blog, I wrote a post covering the evolution of the Australian Army hootchie, the humble “shelter, individual”. In that poorly-written little piece I indicated that the hootchie as issued to Australian forces from the late 1950s onward was the first time Aussie and British Commonwealth military planners had even considered the fact that soldiers might need something a bit bigger than a 7 foot by 3 foot groundsheet to bivouac under in bad weather.

If ever called out on it, I’ll vehemently deny that my incomplete research on the topic led me to being wrong, so rather than call it “new information” let’s all pretend that space constraints on the original post meant I had to leave some important stuff out. Yep, that’ll work.

So what did I miss out? A few things…

From the time of the Battle of Waterloo circa 1815, the British army had adopted the French idea of the tente d’abri (literally “shelter tent” in English). It was a 2-man shelter made from two sheets of linen canvas with a plethora of buttons and buttonholes along the edges so it could be connected to others. Usually two of these tentes d’abri were used, forming a small “A” tent.

Shelter-Tents

US Civil War era tente d’abri style shelter. Usually called a “dog tent” by the troops because it looked like a dog kennel.

The idea is familiar to this day as it had also been adopted by the United States military in the decade before the outbreak of the US Civil War in 1861. The troops there called it a “dog tent” but it was officially known as a shelter half. In the US, the shelter halves were issued right through until after the Vietnam war. These later shelter halves are roughly trapezoidal in shape and when pitched as a two man tent, have both ends closed in. I have a set of two halves dated 1982. It makes a nice, snug and warm windproof and waterproof little pup tent which is great in cold weather.

In British military publications from the 1870s, the shelter was still officially known as the “Tente d’abri” or simply as the “d’abri”. Some time in the mid 1880s, the designation changed to “MkI Shelter”. and it was used throughout the Boer War and into the First World War, also by colonial and later Federal Australian troops.

The dimensions of the Mk I Shelter sheets were approximately 183cm long x 153 cm wide. When two were fastened together, the resulting tent was 183cm long x 214cm wide x 107cm high.

In Australian service, these were used extensively by Australian Light Horse troops during the First World War. They were rolled with a blanket and carried as a swag roll strapped to the rear of the saddle and used as swag-style bedding when bivouacking. They were also used in the camp environment as pitched two-man shelter tents just like the American shelter half “pup tents” of the Civil War.

There was a variant of the MkI shelter which saw the two halves sewn together into a large, hootchie-style tarp, but it seems to have been an interim measure between the Mk I and the Mk II which is described below.

The MkII was more tent-like in design, but could still be used as a tarp if required. It was essentially a MkI sewn up variant with one closed in end. The end of this shelter was made from two triangular sections of canvas which closed using a dutch lacing (grommet and cord loop) closure.

The MkII Shelter became the basic troop accommodation for British and Empire personnel in the field. Later, it was modified with an extension on the rear and a front closed by a pair of canvas flaps. This last model was known as a “Bivy” tent and soldiered on in British Army service until the 1990s. During WWII there was a lighter weight tropical version which was completely mosquito netted, not a bad modification, although it seems to have been used in Europe more than any other theatre of that conflict.

I guess it’d be prudent to discuss the various improvised shelters which were made by troops bivouacking. These were usually two or more groundsheets laced together, or even a pair of wool service blankets fastened together with blanket pins. Surprisingly, these blanket shelters did an amazing job at keeping the rain off, but the flip side was that the soldier had to carry a wet blanket around which weighed a ton and took an age to dry out.

Waltzing Matilda with a swag, Part 7 – Navigation and Direction-finding

Swagmen often didn’t need to navigate “properly” since they followed tracks and roads the bulk of the time. In unfamiliar areas they relied upon directions from other swaggies and from station workers and other locals they might run into and stop to yarn with along the way. In some areas the roads were little more than kangaroo or cattle pads so the swaggie usually had a working knowledge of direction-finding via the sun and the stars as well as other natural cues.

The swag-carrying bushwalkers such as those from the Mountain Trails Club who swagged their way for weeks on end through the dense, trackless expanse of what is now the Blue Mountains National Park, needed to know how to use the map and compass, but since theirs were often the first European feet to set foot on much of the country they trod and much of it was largely unmapped, they also used the lay of the land to navigate. Some of these old time bushwalkers, such as Myles Dunphy, took the opportunity to actually map some of these areas.

Presented here are just a few of the more common methods used by bushmen to find their way in years gone by. For a more comprehensive look at bushman’s navigation lore, see my forthcoming book On the Wallaby Track: A Swagman’s Handbook

Sun.

The sun was the most commonly-used direction-finding aid for those travelling without a compass. Since most bushmen carried a pocket watch, it could be used to find north in exactly the same way we today might use our analogue wristwatch. The 12 was pointed at the sun and halfway between the 12 and the hour hand is true north. This method can be inaccurate in far northern Australia where the sun can be directly overhead and can even be to the south during the wet season.

watch-sun

Finding true north in the Southern Hemisphere using a pocket watch and the sun.

The sun rises in an easterly direction and sets in a westerly direction regardless of where you are in the world, however in Australia it rises/sets generally southeasterly/southwesterly in Summer, or generally northeasterly/northwesterly in Winter.

Moon.

Like the sun, the moon rises/sets in a generally easterly/westerly direction. For more precision, keep in mind that the moon’s orbit makes it appear generally opposite the sun from the perspective of an earthbound observer.

When the moon is in a “crescent” state, it can be used to find the general direction of north in the southern hemisphere. Simply draw an imaginary line through both of the points of the crescent and continue the imaginary line down to the horizon. Where the line intersects the horizon is (usually) true north. For more details as well as a diagram of this method, see http://www.naturalnavigator.com/find-your-way-using/moon

Stars.

In the southern latitudes of Australia the Southern Cross (constellation Crux) method was used to find south. There are several methods for finding the South Celestial Pole using the Southern Cross, but the most common, shown below, uses both the Southern Cross and the two pointer stars.

crux

Imagine a line connecting the two pointer stars. Halfway along this line, draw another imaginary line at a right angle to it and extend this off into the sky. Draw another imaginary line through the Southern Cross lengthways and also extend it off into the night sky. Where the two lines meet is the South Celestial Pole. Now drop another imaginary line down to the horizon. This is True south.

Prevailing winds.

This method relies upon knowing the direction the wind blows from in a particular area. This can be ascertained by observation practice, or from the vegetation. In sparsely vegetated areas especially, trees will usually bend ever so slightly with the prevailing winds. Air from the south will often be cooler than air from the north and wind often blows in from the ocean during the day and towards it in the evenings. These cues, when combined, provide a generally accurate method of direction-finding as long as you have an idea where the ocean lies and you’re within a couple of hundred kilometres of the coastal strip.

Lay of the land.

Much like today’s average bushwalker, the old-time swagman never usually travelled off-track through thick scrub, but if he did, it would have been unusual if he ever became really bushed (lost). Reason being, all that time spent travelling through the country at walking pace gave him an acute eye for the little things, a break in a ridgeline there, a gentle slope there… If you find the watersheds and where they drain, then follow them down hill. Water always drains into more water so eventually you’ll hit the coast, and the coastline where major waterway drain into the ocean is usually populated, or at least visited fairly regularly. The chances of running into a settlement, road or even a decent sized town while making your way to the coast are very good.

Maps.

Often, a page torn from an atlas was the only form of map available. Some atlas maps included towns, roadways, major pastoral stations, waterways and borders, but they were large scale and usually didn’t show mountains, vegetation types or other useful features found on proper topographical maps. As with most maps, the top of the map was usually true north, which allowed a rough orientation to the ground using a pocket compass or an improvised compass rose despite the lack of a useful-scaled grid.

Compasses.

A pocket compass, while nowhere near as precise as a proper prismatic surveyor’s or military compass, was accurate enough for general direction-finding. In use, the compass is opened out flat and a sightline is taken to a distant landmark with the direction on the dial noted. The line of march is noted and while walking, the compass is used as a guide to stay on a relatively straight track, sighting off trees, white ant hills or other landmarks as you go. The closer together your landmarks, the more accurate your line of march.
