Really, I used to get Setchell Carlson mixed up with Stromberg-Carlson, but never mixed up either one with Stewart Warner. Stewart Warner was in Chicago (Belleville, Ontario in Canada) whereas Stromberg Carlson was in Rochester, New York (Toronto, Ontario in Canada). I don't think Setchell Carlson set were ever marketed in Canada, and they don't seem to have been as prolific in terms of models, or production, as either Stromberg-Carlson nor Stewart Warner. Stewart Warner used to manufacture speedometers and other dashboard instruments for cars, and even manufactured grease guns for a time, so car enthusiasts are familiar with the company, some are even surprised to find out that they got involved in the radio and TV business.
