Czech 85mm ID

[MINENAZ16]

Hello,
Found these pictures on other forum,
Does anyone could confirm an ID for this shell.
85mm with hole in base (no visible thread) and remnants of fuze mcz-S30 with VDM device.
Identified as possible drill (školní 85-ČŠk-PLK 44).
Regards

It is possible it could be an 85mm antiaircraft gun HE projectile.
