A super cool example of a WW2 German shell (they were either made in Germany or made on the same exact machinery) with a Finnish liner used by the Finnish military from the 1950s through the 1990s.
These are all going to be used, so expect wear, rust, scratches, and various styles of liner. I have made sure they're functional and not completely trashed, so buy with confidence that you'll get one that's great for your collection.
