Since posting this topic I am thinking of selling the medal and have offered it to some military traders, most are not interested because of the missing pin. Considering the medal is quite rare, only 196 silver clasps were awarded to the Kriegsmarine U-Boat crews, and unfortunately as most of them were killed in action, there cannot be many silver combat clasps still around today. All have agreed that the medal is real, Weitze military, History shop (the only one to offer to buy it) emedals, Sammlerschmiede. I might consider keeping it, and displaying it in a frame, along with this picture of a Kriegsmarine Knight's Cross winner (any ideas who it might be?) wearing the clasp. I have posted a few more pictures of the clasp, they might help in the future other forum members. Dennis
