I’ve found a few of these now, I guess they are rivets but I’m not sure why each is stamped… to me it’d be kind of like putting you company name on every nail… but the thing that bugs me more is they are supposedly from the nearby small town that’s never topped a couple thousand people, so it’s interesting there was manufacturing going on at some point, I can’t find anything about this business on line or even in the local history book written about the city a few years back I’ve asked…
