Please have a look at this Flakkampfabzeichen. (Of course) the seller claims it’s a good one but I have some doubts as the hook looks a bit different than others from this MM, furthermore some rivets are missing at the base of the canon. Could it be a variant or it’s just a fake? And I’m quite surprised by the great condition, maybe too good to be true?

Thank you by advance for your opinions,

Regards,

Pierre
