05/31/2011. Remarks by Jack McKillop and Johan Visschedijk: "The Stearman Aircraft Company of the United Aircraft Corporation built 40 Model 4s between 1929 and 1931 in their Wichita, Kansas plant. The Model 4 was developed as a single-seat open cockpit biplane mailplane with a second open cockpit in front of the pilot that could accommodate two passengers or 600 lb (272 kg) of mail/cargo. It made its first flight on September 21, 1929.

These aircraft were known as Junior or Senior Speedmails or Specials depending on the engine installed and whether it was designed to carry one or two passengers or mail/cargo. Some have said that this aircraft was the last of the luxury styled biplanes produced in quantity by Stearman Aircraft Co. It was a large, sleek, elegant airplane that epitomized the term 'class' and was the ultimate in business biplanes in the early 1930s. Its designer, Lloyd C. Stearman, late in life said, 'It was the best airplane I ever designed'.

This aircraft was built and registered NC784H on July 15, 1930 as a Model 4E Special and was powered by a 450 hp Pratt & Whitney R-1340 Wasp nine-cylinder, single row, air-cooled radial engine giving it a maximum speed of 160 mph (257 kmh) and a range of 600 mls (966 km). Sold on October 7, 1930, this was one of four Model 4Es acquired by The Standard Oil Company of California, Inc. (SoCal, now Chevron), San Francisco, California. The SoCal fleet number was '4' and the price was US$16,000 (US$208,916 in 2010 dollars). With thanks to Graham Slack, Terry Judge and Henk Wadman, here is the complete listing of subsequent owners:

In early February 1965, Paterson transferred the aircraft to Fort William (amalgamated into Thunder Bay in January 1970), Ontario, located on Lake Superior about 670 mls (1,078 km) west-northwest of Ottawa, Ontario. The aircraft had been converted to a crop duster in 1942 and it took him five years to restore it and he flew the restored aircraft, registered CF-AMB on November 18, 1969, for the first time on December 3, 1969. On September 25, 1970, he flew it to Rockcliffe, Ontario with commemorative mail and presented it to the National Aviation Museum (renamed Canada Aviation Museum in 2000), painted and marked as the original 1930 CF-AMB, a Model 4EM (c/n 4016).

The original CF-AMB (c/n 4016) was one of the three 4EM Junior Speedmails purchased by Canadian Airways of Montreal, Quebec and registered on June 2, 1930. (One of the three crashed in December 1931 and a replacement was acquired in January 1932.) The first two aircraft (this and CF-AMC) rolled off the assembly lines without engines and had to be shipped to Canada by rail. This aircraft were used on Canadian Airways airmail routes in Ontario, Prince Edward Island and Quebec until June 2, 1933 at which time it was replaced by more modern aircraft. The fate of the aircraft is unknown.

Canadian Airways was purchased and merged with nine other bush airlines into a new company, Canadian Pacific Airlines, in 1942. Canadian Pacific Airlines was renamed CP Air in 1968 and reverted to Canadian Pacific Airlines in 1986. In 1987, Canadian Pacific was sold to Pacific Western Airlines (PWA) of Calgary, Alberta and the new airline was renamed Canadian Airlines International. In 2000, Canadian Airlines was purchased by Air Canada."
