Spinoffs and derivative companies

• Gormac
  Gormac Products was a spinoff of Gorton founded in 1947. George Gorton III was chairman of Gormac for a number of years. Gormac went into recievership in early February, 2010.
• Lars Machine
  Lars was a spinoff from Gorton (after Kearney & Trecker closed the Gorton division about 1974). Lars built the Gorton pantographs, as well as a line of cutter-grinders. Founded by Chuck Larsen, who was with Gorton as a VP of engineering for a number of years. Here is a brochure published by Lars about the lords prayer effort Lars is no longer in business; they were acquired by Famco Machine.
• Famco Machine acquired Lars (see above) in 1987, and still sells pantographs, cutter-grinders, and parts and accessories for them.
  Famco has the lords prayer engraving on the point of a pin, produced for the 1935 National Machine Tool Builders Association show in Cleveland.
  Based upon commentary seen on yahoo! and google groups, Famco has machine serial number records (a number of individuals have reported that Famco has provided date of manufacture to them based upon serial number)
  
• Kearney & Trecker:
  This company acquired Gorton in the late 1960's or early 1970's (I'm not sure of the year), and eventually became Cross & Trecker and went through bankruptcy (again, I'm not sure of the year, or the order of events).
  Subsequently, Cross & Trecker was acquired by Giddings & Lewis which in turn was acquired by ThyssenKrupp of Germany. See the Giddings web site (history section) for more details.
