Hi again... The writer of the article was Dr. Robert P. Murray, from Winnipeg MB. He didn't mention anything about exports to this country; maybe the sets were sold only in Canada. According to the article, the H. M. Kipp Company was in the bicycle and motorcycle business, and started selling the Mercury Super Ten in 1923. It was designed by Charles A. Lowry, who was an engineering student at the University of Toronto. Lowry left the company in 1927, for a job at De Forest Radio of Canada. He later worked for Stromberg-Carlson (both in the US and Austrailia) and Philco of Canada.

Kipp next manufactured the Mercury Super Power Ten, in 1929-30. The Mercury Jr. was next. Also in 1931, Kipp distributed the Echophone S5 (a US made set) and put their own label on it. At the end of 1931, the company was offering a series of console models, and soliciting dealer franchises. Apparently these were the last radios made under the Mercury name. The author does not say who did the design work after Lowry left the company. It is interesting to note that the Mercury sets which Lowry designed were all superhetrodynes, and the Mercury Jr. was not. The Kipp Company was sued for patent infringement in 1926, so they may have had to stop producing superhets.
