I have just brought home a pair of vises from Dr. John Wittner's estate.
R.I.P., our good man. Your legacy is in good hands here.
Now, I am trying to figure out what I have, here. And the matter of vises, overall.
The larger one (28 pounds!) is called a "utility vise" and has a substantial anvil section and "exposed screw." A Columbian C44, Cleveland, Ohio, that looks like it lived on the back bumper of the Wittner race van. (I wish!)
The Craftsman is a more typical "workshop" vise with 3 5/8" jaws and "just" 16 pounds.
Yes, the "shipping and handling" of the pieces (49 pounds) from Pennsylvania here to Tennessee was *substantial* !!
