I posted a photo of this hammer awhile back, but since then I found something. I thought it was another of the many (shop made project hammers), with the turned head, and turned checkering. Was at the bench, polishing some piece of rust. While looking for next higher paper, picked up some polishing paper, gave the tubular handle of the hammer a few wipes. When I lay it back down the light struck the surface just right. Right in the middle of the tubular part, ====Craftsman===, logo without a doubt. Now There are possibly a few of you guys with some old Craftsman catalogues, Somewhere around 1950 I am thinking?
