Comment, 1) The Canadian Marconi marketing brochure does not mention a  receiver. It is assumed that the TR-15P requires an external receiver
2) The marketing brochure for this radio was found at Library and Archives Canada in the RCMP file #RG12 Volume 113. In the 1930s, the Department of Transport handled the purchasing of equipment for the RCMP so that's .why the brochure was found there.
