another feature is that it's a lot more solder than should be needed, where the head sits on the post. Maybe poor soldering skills… or maybe intentional, to get a more realistic flared detail there. Either way, that seems to say done by hand also?
i keep wondering if these are the only three, or if there are more out there somewhere?
Ah, you assuming they were done at home. That's what most people these days think about when they see a homemade piece. The odds of the maker doing it at home are less than most think. A lot of people prior to WWII did not have the larger machinery at home, thus they did it at their work place.
The soldering is one of the keys to me that says homemade. Anyone who did this for a living on an assembly line was pretty good at it.
I would hope there are more out there, but most of the time they are thrown in the junk pile and discarded.
