No. 422 is a portable power drive for hand pipe tools. No 502 is a portable pipe and conduit threading machine, and No 562 is another complete portable threading machine with wide application for shop or job use as well as many industrial requirements. Unbound from a large 1948 engineering catalog, this unique old one page technical brochure would display beautifully matted and framed.
