Purchased this 40 mm shell the other day with intriging shape. It looks very much like a Gruson but it is only 40 mm in diameter and 112 mm in length.
It has a dummy brass fuze, a narrow brass driving band and a small hole at the top and the base. No markings.
Could perhaps be some kind of a desk ornament but why go to all this trouble when you could use a 3,7 cm instead? So I assume this is the real deal but what is it?
Much appreciated.
