No there not I'm gonna try and refurbish them . My buddy is gonna make me a set of smooth jaws for it alsoFrom the photos, it appears your vise jaws are not completely dead, just mostly. I've taken similar jaws and re-cut the crosshatch using a three-cornered file.
Yes, K M Scott does superb work, but I've bought complete vises for less than the cost of new jaws. Just me, I wouldn't spend the cost he has to get for his vise jaws on that particular vise unless it's for the sentimental value.
