I have a german bayonet deutsche maschinenfabrik ag. It still has the sawback on it. I've read that it was a 2nd pattern. The ears are short, no ring, guard has the numbers 1-992, has the imperial stamp but no date# or letter for which cypher. Right before the sharp edge side has a stamp 7 x or maybe I'm reading it backwards lol. Can't seem to find any markings on the metal scabbard. Trying to figure out the date, rarity, and maybe a price range on it. Anybody's guess? Thanks
