I recently bought a lathe from a terrific gent here in Philadelphia. He has a ton of his father's old stuff that he's been going through. His dad was a machinist at a Nicholson factory that I think was located here in in the area many moons ago. Is there any interest in what I think may be boxes of old Nicholson Made In The USA files? He told me he also has a lot of the steel blanks of those same file profiles. Any interest? I personally feel those old Nicholsons were some of the best ever made. Much better than contemporary stuff from Mexico or wherever else and the steel from those original files may be really great stuff to work with if you're a tool maker.
