Vanished Tool Makers: G.M. Co. Manufacturing Inc., Long Island City, New York

Below, a couple of "Unbreakable" brand clamps:



The smaller clamp is stamped "G.M. Co."


Below, a stamped metal square made by the same firm:




This company is not, as you would suspect, General Motors, but a manufacturer that made a variety of tools, as shown in the 1951 Popular Mechanics ad below, and in the pics below it.  That's the extent of the information I can unearth on the company.


The Family Handyman, May 1955
Below, some pictures considerately sent in by a visitor who notes, "these are examples of the small 1/4” square drive socket sets that G.M cranked out by the millions (my best guess based upon how frequently I see them on Ebay.):"  Many thanks for these images!





Note the unusual button for selecting the direction in which the drive turns:

I recently found a 'spray gun' part no 17b manufactured by this company. It's basically a airbrush you run off a spare tire according to the box.

It seems that the car company wasn't too upset by a tool company sharing their name.
