Found a photo showing the canvas cover for the slide rule. I think I will make the brackets and a cover like in the photo, and give the appearance of rule being in place.
Do I understand correctly that the instrument was 23" long x 2" width? I have a very nice piece of 6mm thick aluminium plate that would fill out a canvas cover quite nicely. I can get the bracket dimensions and footman loop placements from my local gun, but are there any other specs or info I need to get this right?
One more question. I have seen many variations of finish on the 'head' of the range sticks, and even seen some partially painted red, so my question is.....how are they meant to be painted?
P.S: I take it that the chap in background of the 25pr photo is probably NOT interested in military history!
