Military pin

[Older The Better]

I came across This pin in a box of things my grandma was sorting through to downsize. You guys helped me on a 2nd Calvary pin already I suspect this is another Calvary pin but I don’t know what the b is or any idea how old

US Army 4th Calvary Regiment B (Bravo) Squadron, Troop, or Company can't remember Army units like I can Air Force units.

Thanks If I had to guess I would have said the b was for battalion but I suspected I was wrong

The screwback fastener dates it to the WW1 era, but before WW2

Thanks for the id my grandma said her dad didn’t say much about his family. Things that may seem obvious things to know about your own family are a bit of a mystery. Now I’ve got a time frame and a company shouldn’t be too hard to figure out who’s pin it was
