I'm pretty certain that I have the correct guy for the "H Atkins" helmet and if those helmets were obtained together I'm pretty sure both belonged to this person.                         Ancestry - Harold Atkins .pdf Passport Application - Harold Atkins.pdf Possible WWII US Navy Muster Roll - Harold Atkins.pdf US Census Records - Harold Atkins.pdf WWI US Army Transport Record - Harold Atkins US Navy.pdf

Thanks guys. That's helpful.

Thank you very much for your observations, gentlemen.  I'll put them down as two votes for "not the real deal."  😀

Here’s another shipyard helmet I have.     

When I was in the high school band, our uniforms were modeled after the British royal bands.  The uniforms looked great, but we didn't get to wear a bayonet! Marv

Welcome from a Husker!

Thanks for the quick input! I am not familiar with militaria insignia so this little titbit is interesting that there could be another piece. The ring has a spring mechanism that opens like a necklace catch. I was entertaining that means it could be worn as a pendant but it would be upside down 🙃  I don’t have a coin handy but used a ruler, it is about 1 1/4 inches across.   

That’s really nice!  I would say you are correct in believing it is a sweetheart pin- a gold chain would connect to the other missing part.  The missing part may be an officer’s rank insignia.   Based on the direction the eagle’s head is pointing, it is post 1941 manufacture.   Can you post another photo with a coin next to it to provide size context?

Hi all, I collect vintage Tiffany items and came to acquire this badge, which from my limited research seems to point to a navy officer beret badge? It is sterling and 14k gold. I am curious what that ring at the bottom might be used for. To attach a chain to keep the brooch safe? Will this be a sweetheart pin?  It weighs 7g in total.  thanks for any insight!
