An other kind of badge for which I have no experience at all… I have seen this U-Bootskriegsabzeichen on sale. Of course the seller claim it’s an original but I have doubts, can you confirm it’s a good one?

If yes, we see on the pics it is very vaulted, is it common on this kind of award (as we can see on some Nahkampfspange for example)?

Thanx by advance,

regards,

Pierre
