Hi and you've already heard enough ' no's ' to convince you. It's an awesome image even without a military touch! They're pre-war, if you're having a shot at tracking them down.
Those buckles, I mean the type of closure seem to have been common? Not an expert at all, family just for some reason has a ton of odds and ends passed down and passed down and passed down- few of these. It's unclear why we keep doing that since they get uncovered, someone says " Look! Belt buckles, cool! " then packed away for the next generation to do the same thing.
Welcome to the forum, feel free to share any more images. Thanks for bringing this one here!
