Maybe russian 76,2 mm shell of anti-aircraft canon model 1931?
Recently I found this bottom half of a shell but I can't figure out exactly what shell it was.
It had two driving bands, the lower one is still intact but the upper one is missing.
Maybe this could help to determinate it, as the rifling marks are visible (32 of them) and the knurling to fit the driving band is visible as well.
My initial thought was that it might be a 17Pr due to the double driving band, but this is contradicted by the fact that the shell is missing a crimp groove, and the rifling marks seem to be too narrow.

Thanks in advance,
