All,
Just acquired a lovely 1938 S/42 KM piece. It is Nordsee marked on front grip strap, and a high 90s% gun. It was very, very stiff opening up for examination and appears to have been fired little if any. The disassembly revealed generous quantities of old grease that was beginning to crystalize and contained some fiberous material. Sniff test tells me it is OLD.
Will send pix to someone who understands the mumbo-techno-jumbo
required to post them here.
