I recently acquired this inert 37mm cartridge. The cartridge has been turned into a lamp and that was in fact the reason why I bought it! The cartridge is made by the Norwegian company Raufoss Patronfabrik and I think it is a Norwegian 37x302R cartridge. There are several markings on the case (see pictures) but I can’t make out the production year. I would be very grateful for any information regarding this cartridge, especially what gun(s) it was made for.
