Colleagues, I really need your help!
Tell me - on tanks Mark IV and Mark V were the same guns? Hotchkiss 57 mm, which had a barrel length L23?
Photo from my application is valid for tanks Mark IV and Mark V?
Sometimes it seems that the gun barrel on the Mark IV is longer than the later tanks.
Mm that didn't work, I'll have to work out how to post pics.
There doesn't seem to be many images or drawings of these guns, I received couple of drawing from the tank museum (Bovington, the only drawing they have) but they show the original naval guns, on one of the drawing there are some hand written measurements plus a line cutting the barrel, the first figure is total gun length, the second I take as being the short barrel measure, these figures are near the wiki figures.
97.63 metric = 2.479802 metres
59 metric = 1.4986 metres
Wikipedia gives the following for the short barrel fitted to the Mk IV/V
Bore: 52.12 inch (1.32 m) 23 calibres
Total: 60 inch (1.52 m)
Bovington have on display one of the short barrelled guns that would be ideal for measuring.
