Schwerin U-Boat Timeline--Major Revision to study

[Darrell]

Guys,

I'd like to start a pictorial discussion on the "evolution" of the Schwerin U-Boat Badges.

I know there are a ton of threads with Schwerin U-Boat badges posted here throughout the years. I don't want to start lifting pictures to post here without obtaining the owner's permission.

Therefore, if you could please contribute. I'd like to see any variation, Tombak, Zinc whatever. What I'm focusing on is the reverse hardware and obverse eagle characteristics.

Thanking you guys in advance. Hopefully we can get some good discussion. Please try and post some decent Obverse / Reverse pictures (scans or high res). You can post nice closeups of the catches, pins, and hinges if you like.

Thanks.
