This small vintage vise with bench clamp is used but fully operational. It's worked hard so it deserves to be in a great collection rather than on a work bench.  It appears to be made from cast steel and has the original green paint. We can find no markings. The closed dimensions are 5 x 1 ½ x 5 ½ inches.  Jaws open safely to 1 ½ inches.  Note the slot cut into the right side of the movable jaw.  I wonder what they were thinking??  Weight is 1.3 lbs.
