Hi,

Could this be Bofors case manufactured 1939 by ENZ? What ENZ stands for?
Diameters 4 cm x 31 cm.

Mystery solved. Found after a long search: "enz WW-II German ordnance code assigned to Enzesfelder Metallwerk, Enzesfeld plant, Vienna, Austria"

The answer is yes. The Germans captured a number of Bofors early on in the war and manufactured their own ammunition for them. Unusual but not unheard of.
