It looks a awfull lot as the german 21 cm mortar.

There are 4 variations of the German 21cm experimental mortar projectile. They came from a burial site on one of the proving grounds/test ranges. I'm thinking it was Hillerleben. There is a document of the projectiles found there.

Seems like more than four, if you are referring to the Skoda pieces.

At least 4. In the photo I saw, there were 4 variations in the photo.

There is a problem, the body diameter is about 15-16 cm.
