I have a ? Have Friedrich Orth made U-Boot Badges in Tombac ? I saw one at the Show in Letohallen . I dont have any pics of it , but maker mark looks correct , hinge , pin and catch looked like FO . But badge had not any finish left , and price was a bit high , so I past it . And the coulor looked very dep/dark brown on tombac . And instead og the ring (o) in the other position for catch it had a (#) quadrangle . Pin was vertical , and this ( # ) was at the lower position on whreat ( six o`clock ) . Held in hand it dont gave me this 100 % feeling , but details on front was good . Have anyone seen or handle a FO U-Boot Badge like that , fake or real ? Jan Arne
