Follow-up to my original post ...
That second saw from the top turned out to be the person spawn of an illicit union between an 1880s-era Disston, a 1920s-era Atkins and a Warranted Superior (those were the three medallions someone had shoe-horned into that poor handle)
Instead, I brought home the big ripper (2nd from bottom) -- 4½ PPI and straight as an arrow.
I cleaned it up enough to get the plate smooth and revealed this etch.

Research shows that Walbridge & Co was a Buffalo, NY hardware chain from 1884-1926. At one point they had 5 stores and a warehouse. The flagship store occupied the first 3 floors! of this building, which stands to this day.

The saw appears to have been a Disston product, engraved for the reseller, but I can't find a good match for it among any of my catalogs.
