I picked this alloy clamp up recently. I assume it must have been designed for some tire repair procedure, maybe bead breaking, and would have been made for Goodrich by someone else.
The screw is just a 5/8"-11 TPI thread, not an Acme thread. I don't know if it was original with the tool, but, aside from a special purpose, such a short screw on a clamp is like T-rex arms--not very useful.
I ended up stripping off of the old paint, sandblasting the clamp, and making up a new screw to return the tool to use as a regular C-clamp. Came out rather nicely, if I don't say so myself.
Anyway, a B.F. Goodrich branded clamp--how cool is that? Maybe it was used to demount tires from a Lightning P38!
