Gents, As it is extremely rare, I would like to show you my tombak unmarked u-boat badge attributed to Boerger & Co., Berlin - Beco. It still has just incredible amount of gilding left compared to few other known examples. Enjoy! Kind regards, Hubert

Obverse. Cheers, Hubert

Yes, it is tombak variant but these horizontal pin Deumers exist also in zinc. Here is my zincer for comparison. Cheers, Hubert

As requested. Unfortunately, can't recall where I got it from...

More pics - second one.

Hi Norm, Agree, it is very resonable explanation In my database I have two examples of minesweepers with flat-bottomed "C"s paired with dome-headed hinge pins. I'll try to post the pics. Cheers, Hubert

Hi Norm, Sorry, I was not precise enough. In my previous post I was refering only to flat-bottomed "C" catches subcategory, and agree that in this case it's very hard to tell individualy without a risk of being wrong. Only a number of individual opinions may secure its correctness or long years in this hobby which I lack, unfortunately. Here is another opinion from Mike's great article: http://members.iinet.net.au/~datumgeo/Schwerin-Article-Sectioned/7HingePinCatch/Schwerin_HSF-HingePinCatch.htm Cheers, Hubert

Hi Norm, I would tend to say the opposite - flat-headed hinge pin, with or without crosshatching, or simply 'beheaded' paired with flat-bottomed "C" catches are still less common. But this is mu subjective opinion, might be wrong. Cheers, Hubert

Hi Norm, According to my observations I'd rather say that round-bottomed "C" catch is in fact correlated with dome-head hinge pins but later (zincer-like) flat-bottomed "C" catches could be met with all types of hinge pin heads and situated on both sides of the hinge. This is at least true in Schwerin's minesweeper line. Cheers, Hubert
