Hi,
So far, the most favored guesses appear to be: suspender clasps, cuff links, belt pieces, or regalia items of some kind. We have yet to find anything exactly like them, although we're still searching. One friend of mine thought the pieces may be hand-made and not machine-manufactured. If that's the case, then they may be one-of-a-kind items, but then it looks like they would be monogrammed or something of that nature. Oh, well! Hopefully, eventually, we'll find out more about them!
I sure appreciate everybody taking the time to post pics and suggestions.
