I picked up a Record 34P 4-1/2" vise which I understand to be pretty rare in the US. Paid too much for it, but I got out my can of turd polish anyway (hot water, simple green, brushes of various levels of aggression) and managed to bring it back to (mostly) the factory enamel blue. Love it when guys hastily spray paint vises, especially with dirt underneath.
As found:
Halfway clean:
Totally clean and on the adapted swivel base:
It's been well used but not abused. The worn jaws still close straight and the screw/nut has no visible wear. The vise has some pretty cool features. The nut floats in the body and the screw is supported on both ends of the slide. I like how the slide and body have huge ribs to efficiently bear the clamping load, rather than just a ton of metal that is not well utilized.
The jaw insert screws are tapered and are *almost* an M8-1.0 thread... but they are in fact BSC 5/16-26 (British Standard Cycle - who's ever heard of these dang things before?!)
