GT: it's been listed for awhile now. it looks like one of the jaws might have been welded or is broken, but not sure. it is either a Parker or a Morgan because they both made that same vise.
if he wasn't $500 the stand might make is worth looking at.
Gurus can chime in to correct me, as this is guess.
Unrestored, that $500 is wishful thinking. Maybe $150 to $200 if there are no welds or other repairs in it's current condition . . . with maybe $50 to $75 more for the stand.
