Doc, here you are. You can see that the milsurp hinge pin boss is entirely too large and clunky while the Albright pin boss is little more than a grooved bulge with the hinge pin held in the groove by the spring tension.(spring swung aside for clarity)
Your nondescript buttplate in question is one that Herter's sold back in the day. Don't know who made it but Herter's was at least one outlet for it. It's on a par with the Niedners, i.e. slightly thinner than the Wins.
BTW you guys, please don't send me any money for postage, just pay the favor forward to some other aspiring smith down the road sometime. That's what I'm doing right now (and you're helping me), I'm paying forward some of the past favors from others that it's now too late to pay back to them in person.
Regards, Joe
