Some Fairmount tools are quite collectable.
As long as I know, the ones marked Fairmount Cleveland are of prewar manufacture.
Fairmount was among the suppliers of tools to the Government in WW II, and also supplied tools for the Willys jeep toolkit in war time.
I have never seen a Fairmount screwdriver, but Fairmount was mentioned as possible supplier of screwdrivers in a Willys Overland drawing: I sure would like to see one.
I do own ball peen hammers, open end wrenches, adjustable auto wrenches, pliers, all made by Fairmount in war time.
