 As usual the service info posted on Nostalgia Air is borderline to useless. The reason being is that whilst they scanned them whoever posted them presumably tossed out the frames of reference, RCC sheets have a model year marked right on them such as 1938-39 or 1940-41 etc., but rather then just using the RCC sheets they put U.S Rider manual sheets in there. Them must have assumed that Philco of Canada models used the same system that they did in the U.S, well they did to a point but many numbers have a 3 marked in front of them like 39-3116, or 38-3116. I will have a look in the Radio College manuals for this model 44.
