I looked up some on the net and they seem a bit different. Same proppelar style crossgaurd but the scabbard is different. There seem to be several variations out there and look to be German made for yugo,possibly Solingen. The first naval dagger I posted was made by Alcoso as can be recognized . The others I posted seem to have the same look or are at least Geman made. The one you posted looks awfully new but better images are needed to be sure, IMO . Get more info from the seller, I.e. markings, and so on.
