History
In 1922, William D. Shaffer founded the Shaffer Tool Works in Brea, California to supply the oilfield industry during the second Santa Fe Springs, California oil boom.[1] The company was incorporated in 1938.[2] Shaffer bought the oil field equipment business of Alco Products in 1962.[3]
In 1968, Shaffer, except its Houston, Texas-based Bayport Fabrication division, was bought by Oakland-based Rucker Corporation for US$2.7 million[4][5] and changed its name to Rucker Shaffer.[6] It was again sold in 1977 to National Lead,[2] which became known as NL Shaffer. In 1979, NL Shaffer purchased Koomey Control Systems. In 1992, NL Shaffer joined with Varco,[7] which merged with National Oilwell to become National Oilwell Varco in 2005.
