Will consult with the proof house.

Does anyone have dimensions of a mk1 barrel which has the tapered and flared end?, or know of a museum in the U.K. Which has one ?, as pictured.

Thanks

Gents,

I've been to bovington tank museum and measured a 2pdr barrel in a Valentine tank. Ive attached a drawing here, the muzzle outside diameter at the tip is 2 7/8". The 53 1/32" dimension comes from a later stepped barrel.

I've read on the internet there are two lengths of barrel, one with an overall length of 81.89" designated L/52 and an L/50 with an overall length of 79" although I've not read this in any official war office publication.

Does anyone know or has a MkIX or X barrel to confirm its actual length when removed from the breech ring?

Thanks Kevin.

Kev did you check out any measurements of the 2 pounder barrel with little John attachment displayed at Bovy? Ron

[kevin powles]

Ron, yes looked at that but it's a later style and difficult to measure with the adaptor and ring on, but only found out about the L/52 and L/50 when I got back. Do any of the two total length measurements correspond with yours?

Here is the one in the rack at bovy
