A year or so ago there was a long vise thread where all sorts of vises were displayed but no swivel jaw, a type I confess to being totally ignorant of. I've just been given this 19th century example when my friend was cleaning out his 18th century house.
It has a swivel base but no obvious way to keep it still. It looks like the swivel jaw was tightened without the securing bolts (one missing) tight as a piece is missing. After a quick bead blast the replaceable jaw still has a good pattern on it.
The movable jaw is spring opened but the slide is too dirty/rusted to let it happen although it's not stuck. Overall it's in good condition with no real signs of hammer marks or other abuse except for the swivel jaw.
Does anyone know anything about this vise or swivel jaw vises in general.
Thanks!
