Manufacturers of fine small tubing, from 5/6" OD down, in many metals. Unbound from a large wartime 1945 engineering catalog, this unique old four page technical brochure would display beautifully matted and framed. Great cover graphics. A fantastic addition to your retro metal library. Pages may be detached and contain a small amount of residual glue on edge.
