Very interesting shell, I think it's a Jugoslavian shell for 22cm mod 28 skoda, 22cm Mrs 538(j). Used by Poland too.
anyone has info please?
best regards
It certainly looks like one. There was a picture of wooden mockup of a 305mm skoda projectile earlier in this thread.
I have only info on the 22cm Gr 40 with german nose fuze.
