Trying to research the Garland mortar on line is not a very satisfactory activity, there are a few contemporary photos, and one and half surviving examples. Even the complete’ish one is thought to have a short barrel.
Looking at the one photo available on line it would appear to have a simple L shaped handle to the rear which may have been used for traversing the piece. Closer inspection however shows there is what appears to be a single leaf spring underneath it. It then appears to pivot at the base, with a small arm running up and into the top part of the mounting block, and may even end in some form of a pointer, or so it would seem. Clearly this arm is doing a lot more than just being fixed to the base block.
The description states that the barrel is fixed at a set angle; however there is a range plate in yards on the top. In order to change the range, you either change the angle of the mortar. (This can be clearly seen in one of the contemporary photos of the piece being fired, off a couple of crates with a large wedge visible under the wood block). Or you alter the quantity of the propellant charge. Was the propellant used just ordinary black powder, and if so where was the touch hole, or how else was the charge fired, and did it fire ‘Jam-tin’ bombs . One Wikki source states it fired a bomb with a “white calico tail”, any suggestions as to what they might have been.
Is there an Australian Pal out there who would be kind enough to take me a couple clear photos of the mortar, including what was on the range plate? I would love to make a replica as the War Diary of the 8th
Hants state they were issued with two. It could then go with my leach catapult, but this will have to be non-working replica.
