Polish Vickers 6 ton tanks.

[toque]

Vickers developed a 6 ton tank for export. 38 were bought by Poland.

Polish designation: VAU33-dw
16 x Vickers MkVIE Type A. Twin turret. MG armed

Polish designation: VAU33-jw
22 x Vickers MkVIE Type B. Single turret. 47mm/3pdr low velocity gun, coaxial MG.

Does anyone know ...

The British designation for the 47mm/3pdr gun?
A sample was sent for evaluation to Finland but was rejected. Did it turn up anywhere else?
If the Vickers tanks were taken into German service after 1939? I can find no trace in any beute list I have seen.

British just called it

3 pdr 2 cwt

as far as I know.

That one was made in 32 and 40 calibres.
Here it is:

The one I have in mind seems to be something quite different. Here it is currently sitting in a Finnish museum:

Given the resemblance, might it not be French derived?

BTW I have now found a Polish website that denounces the VAU designation as a post-war invention. Apparently it was just known as "Vickers 6-tonowy". Given that the Poles were very literal in their designations, I am inclined to believe this.

That 47mm is pretty weak. All other 47mm from different countries have muzzle velocities over 2000 f.p.s.

The RN did possess during WW1 some 80 examples of a 2.5 pounder (47mm) Hotchkiss gun, which had a short barrel. That's the only one I know which might qualify. See: http://quarryhs.co.uk/47mmUK.pdf for details inc photos of the ammunition.
