Old shell head.

[Panzer 3]

Hi,
I was given this old shell head today from a lithuanian friend who brings pieces back over to here, i know it is a bit tatty at the moment but i would like to restore it to some sort of display piece. I need an ID on it though, im thinking it is Russian as the only markings on it are these but the " B" is backward ( B C ) the marking is on the top ring,
it messures 7,3/4 " high, 2, !/4" Dia, the drive band is 2,5/16". the outside of the top ring is 1, 9/16", inside 1, 1/8 " i know you all like a puzzle so im hoping someone will know something about this.

Hi,
I am in the second stage of the restoration of the shell head, i found it is a russian 50mm shell, so im looking forward to putting it into it,s colour and iv ask my friend to help get me the fuze for it. So i hope when he goes back home for his visit he can find one.
Dave.
PS It was measured wrong at 2 1/4 " but it is 2" so 50mm
