Mk IV & Mk V Hotchkiss 57 mm guns - Need help!

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. 


Please tell me the answers to the gun 57mm Hotchkiss - Is my drawing correct? 
Give me the other dimensions

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.

I think that the shorter gun is just the Naval variety cut so use the plan and make the barrel the length required.

The British naval gun is different in style to that carried in the A7V due to the differing uses of the original weapons.
