I found this set of removable pipe jaws in a shed on my wife's family property. They appear to be from an open screw bench vise. The only identification on them is the number 5 and a c in a circle. Based on the dimensions, the screw would have been 3/4" diameter and the beam below it would have been up to 13/16" wide. Dimensions are:
Height (overall) 2.75
Width (overall) 1.85
Slot width (at screw) .75
Slot width (at beam) .85
Slot height (at beam) .35
Slot height (above beam) 1.125
