I take it back... the polar bear was NOT when it was sunk in 44, but was from a British report after the sinking of the steamer Michael E. on June 2nd, 1941! I honestly dont know what the crew wore as their tradition pin, if they wore any at all. I did a quick look through my photos and books, as well as the members section of uboat.net, and cant find any pictures of the crew wearing a pin, or even a picture of either the shield or the polar bear on the conning tower! I will keep digging around though... maybe I will come up with something.
