Brink & Cotton C-Clamp No. 142-2 inch
This is a nice antique 2.0 inch capacity C-Clamp with the cast steel design, marked "B & C. CO. BPT. CONN." on one side and "142-2 INCH" on the other side of the frame. It is of a nice quality cast iron with a nicely finished frame casting. It's in very good useable condition with no rust, straight, not bent, good threaded rod. This type of C-Clamp is made of top quality steel and is heavy duty, so these could be used in metal working.
