"There is no doubt that it has seen better days, but given its age it seems pretty remarkable to me that it even exists, let alone here in the US."

Except that it's not a bead. It's an odd flattened shape that looks rather like the profile of an airgun pellet. Look at the way the light plays about the top. It is not a sensible silhouette for aiming through a peephole.
The only thing I can say to that is the sight picture is soooo long that you can barely even see that post way out there and I have good eyes. Through that tiny peep hole, that brass post looks like a pin head.
