I recently acquired this 47mm explosive round and need some identification help. The case is 384mm long and headstamped "ENZ 1915 20". The projectile is a high explosive type with a base fuze. It is 175,5mm long without the fuze installed and has a deep explosive cavity about 141mm long. There is a proof mark visible on the projectile body and bottom of fuze that appears to be an intertwined S and W within a circle.
I think the ENZ headstamp means the case was made by Enzesfelder Metalwerke in Enzesfeld, Austria but that's as much as I currently know. Is the round for use by Austrian Forces or export to another country? Significance of green band? Is the S-W proof identifiable to anyone? Naval? Coastal defense? Other use? Any help appreciated.
