37 x 288 experimental, Czechoslovakia

[Sorcerer]

In collection I have this interesting Czechoslovak 37 x 288 experimental round. It looks like scaled up 30 x 211 M53/59. Case is made from 2 parts and is intended for presure test barrel. I have no information about this round, maybe someone else?

I can't help you with an identification on this one but I like it, a lot, very nice.
Does the projectile come out of the case?

Thanks for the response, do you have any more detailed information about this project?
The projectile is solid and is stamped + 2 52 so it corresponds to the period you write about.
