Camco bought the design rights from GE in the 70s about the time they merged 5 Canadian brands ( GE, Hotpoint, Moffat, McClary, and Beatty). In the late 70s, Camco started making the Beaumark appliances for Simpson's and the Bay department stores. In the early 80s, Eaton's Viking branded appliances were made by Camco also. I don't recall exactly when Mabe from Mexico took over the Camco operations (probably mid to late 90s). Most of the brands were phased out and the whole operation shut down in Canada just a few years ago.
The McClary washers were fun - I had a washer and dryer set from McClary in the first house I rented out. They lasted longer than any set that came after...
