Actually, this set pre-dates the Camco takeover of the McClary brand name (which had been around 1975-76, IIRC)... This pair looks to be from the very early 1970s when McClary-Easy-Beatty were still aligned and the washers and dryers for the Canadian market were being built at the GSW plant in Fergus, Ontario. Here's the fooler - Beatty had on and off alliances with Easy and Franklin over the years but this particular washer is an Easy design for sure. I spent a loooong time digging in the archives at the Beatty Brothers museum a few years ago, looking for for clues about my oddball 58 Dominion and eventually finding that it was based on an Easy of Canada design!!
After the Camco buyout, McClary appliances became Hotpoint clones - the washers were not fantastic as they lacked a 'rim-flo' filtering system but they were sturdy damn things.
McClary was seen as a 'low-end' brand and was typically sold at independent furniture and appliance stores and at discounters back in the day (Bad Boy and Krazy Kelly in Ontario and Faucher Le Roi Des Bas Prix here in Québec come to mind).
