06/30/2014. Remarks by Johan Visschedijk: "Archibald S. Barkley and Harold B. Grow, both aviation pioneers in the United States, had joined forces and formed a new company in Wayne, Michigan, to developed an eight-seat twin engine plane which they called the T8P-1 (Transport, eight-seat, first model) but which became generally known as the Barkley-Grow. It was a modern all-metal machine not unlike the Lockheed Electra. Unlike other similar aircraft of the era it did not have retracting wheels and was easily recognized by the unique wheel pants or faired landing gear. The prototype was initially registered as NX18388 and first flew in April 1937.

Canadian Car and Foundry (CCF) had acquired the worldwide sales rights outside the USA for the T8P-1. When the aircraft was certified in the USA it became NC18388 and CCF staff pilot Victor John 'Shorty' Hatton took it on a long demonstration tour of Canada in October and November 1938.

Barkley-Grow had demonstrated the design to the RAF and, in an expansion effort aimed at finding enough money to develop a newer version (T8P-2) with retractable gear for the RAF, had run into financial problems. To prevent its existing aircraft from being seized by creditors in the USA, the company eventually moved them into Canada where CCF attempted to sell them. The fixed landing gear could easily be fitted with skis or pontoons, hence seven of the eleven aircraft produced ended up in Canada.

The pictured aircraft was first registered on August 26, 1940 to MacKenzie Air Service. Sold to Canadian Pacific Airlines in 1942, and to Associated Airways on March 20, 1950. Later it was owned by Pacific Western Airlines, F. Baker, Sioux Narrows Airways, Parsons Airways, Northland Wild Rice, and Northland Airlines. It is preserved at the The Hangar Flight Museum, Galgary, Alberta."
