RTM - another thought - I was dismissive of Masonic connection also because a machinist hammer doesn’t seem relevant to symbolic ceremonial reenactment. I would more expect a mason hammer.
I did, however, search for lodge #34, and came up empty in PA (a handful in other states). I did see a couple mid-Atlantic FOP #34s, but a machinist hammer seems even less relevant to that organization.
As a lifelong PA resident, the keystone symbol is so pervasive, I doubt its connection to almost any specific organization, including manufacturers. And as you pointed out, seems unlikely a forge mark would be repeated so haphazardly. And I don’t doubt Stanley made their own hammers - didn’t they buy out Atha for that specific purpose?

Not often I see a style I haven't seen before!
