Vises-over the span of 40 years or so, X-Acto used many different mini ( 1" to 1.75" jaw width) hobby-type bench vises in their larger sets- the 88, 88n, 89, and 99 sets. They were from a variety of manufacturers, mainly in the US, Japan, UK, and later, Taiwan. The earliest vises actually came from the venerable US company of Brink and Cotton Mfg. of Bridgeport, Conn. Their vises were simply marked BC (see 1st photo). The Japanese vises were usually painted metallic blue, green, turquoise, or gloss red, some with red-painted jaws. They used two different designs; one had fixed front jaws and moveable rear jaws (similar to the German Boley vises), and the other design was more conventional, with fixed rear jaws to the body, and moveable front jaws. The better vises had double guide shafts, and a center screw shaft. Most of the US made vises were painted black, red. The rarest vise is marked X-Acto USA (2nd to last photo) was their #389. The large sets featured a small shelf for the vise to be clamped to. This shelf is often broken off; in the later 89 sets, it was braced with a vertical piece of wood (last photo.)
