This is a very nice, clean, 2-1/2" capacity C-Clamp, marked "BRINK & COTTON MADE IN U.S.A. 142-1/2". This one is in very good condition with very little wear noted, and little sign of use. No damage, no rust, clean. This clamp weighs 7 ounces, and has an 4.5"; long frame and the thickness at the clamp pad is 5", and the threaded screw is .31"; diameter. The reach clearance is 2.37 from center of the thread rod. A very well made tool, by a well known tool maker!
