4 Antique C clamps and 2 have the early T. Eaton logo although one logo is not easy to read. All 4 are rusty but all 4 work like they should. 3 of them measure 3¼" across the opening and 2 5/8" between one end of the opening to the plunger when it is completely opened. Those 3 screw all the way closed. The fourth one measures 2¼" across the opening and 2 1/16" between one end of the opening to the plunger when it is completely opened. This one does not screw all the way closed. When screwed in all the way there is still about an inch of empty space remaining between the plunger and the end. You get all 4 clamps
