I have other military WWI, WWII, Vietnam war collectibles and unique items listed. Here is a vintage USN anchor pin for a hat or cap (I’m guessing). I could not find any markings. It’s well made and nicely detailed. This came in a lot of stuff from WWI era, but it may be older. Please see pics for more details. I HAVE NO CONTROL OVER IT. VOTE TO CHANGE THINGS!
