An old hardware store and lumberyard in town closed and they had an estate sale. This place, about 2 miles from my house. Lots of treasures in there in hidden corners, but the tool is older than that business to be sure.

Interesting for sure. Now I guess you are going to have to carefully wire wheel that thing, scour out the socket and try to find some stamps or engraving, markings and evidence of use. For instance, if it was used along sidewalks even for a short time you'd see hard scrapes along the blade and it would not be fine knife edged.
