Electrohome, based in Kitchener and widely known, was one of Canada’s largest manufacturers of consumer electronics at the time, ranging from food mixers, fans, humidifiers, and car radios. 

They also specialized in furniture-styled radios that could “fit into any furnished home”. Besides being involved in the home entertainment industry (phonographs, radios, television, etc) they also had a floor of their production plant dedicated to creating furniture. Electrohome sold its own branded radios, but the RM–315 was sold under Eaton’s brand name “Viking”. The brand Viking was a private label exclusive to Eaton’s, which may also explain limited documentation

The book titled 'Visionary thinking: The story of Canadas Electrohome' mentions that Electrohome specialised in furniture-style radios that could “fit into any furnished home this is further supported by the description of the radios in Eaton’s 1950-1951 catalogue, with specific examples used to demonstrate how different colours can fit into furnished homes.

The RM-315 fits the ideology of the company but likely was not the company’s main product type, as it is not a furniture-style radio. This may explain the further lack of mediation of the product and the reason why the RM-315 and lookalikes are sold for lower prices than cabinet-styled radios.
