I'm very sorry to have to say that I agree with Ger, and the military style markings on this miniature are completely bogus. In between the WaA253 and WaA519 Waffenamts WKC did use a WaA883, but not the marking posted here. And the Waffenamts were German Army markings - NOT Naval. A mistake that has been made on full size Diver's Knives from at least one U.S. source that I know of that I suspect some buyers of same have in their collections that are 4th Reich fantasies. The markings here having some other characteristics of PW fakes. From my perspective putting this knife in the same general category as the bogus/alleged "SS - RZM" marked letter openers.
