Lot of 5 large old C clamps. These are Hargrave Superclamp No. 44 made by the Cincinnati Tool Comapny. They are heavy forged iron with 6 inch throats and about 9 3/4" long over the clamp bodys.
These all have a patina of age and some minor rust. One clamp is missing the flat end or foot on the clamping screw.
