Can anyone ID this WWI era 80mm Artillery Projectile?

Hi:

Just picked up this Unusual WWI era Artillery Projectile.
and was wondering if anyone could identify it.

It's 80mm , and 29cm long. (about 11 1/2" ).

has a threaded hole at bottom for fuse.

NO MARKINGS anywhere that I can find.

Some references say that German's, Yugoslavians
used 80mm.

Does anyone know more, or a better place to ask.

Post or PM

THANKS in advance.
