One of my odd ball Russian shoulder boards, can anyone tell me more about it and time period. I am assuming armor

Here are some visor hats I recently added through a friend. can anyone tell me more about them?

Thank you! A Sherman tank would be fun😁.    Actually, the Bren was so much fun I may do something like it with a few junk M1 Garand bits and pieces I came across. If and when I decide to start playing with it I’ll start a thread on the USMF.   

Great piece! Amazing piece of history! And something you see every day... thank you for sharing.

Well done that man. What's next - a Vickers MMG!

definitely close, but different shape...

Blue skies, Brave Sir, Blue skies...

Super cool and great back story! Beautiful bicycle.

Looks to be a WWI or WWII German Miners Association button. 

The Luftwaffe pilot/observer badge in the photos came in a grouping and I suspect it to be a reproduction piece but wanted to have others with more experience weigh in. The reasons for my suspicion are the block type hinge which I don’t believe this maker used. Also the makers mark doesn’t seem quite exact as other examples I have viewed in pictures. For example the “L” in Berlin doesn’t use the same arrow shaped letter as I see in pictures.  These are a few of the reasons for my suspicion. 

Not really my area of collecting, but here are a few I picked up over the years.

R.I.P.
