Designed by Georgian expat Mikheil Grigorashvili (anglicised as Michael Gregor) and built by the Canadian Car and Foundry. It was tested by the RCAF against the Grumman F3F and while it outperformed the Grumman, the Gregor had no military equipment fitted. CF-BMB competed in the All-American air race from New York to Miami in 1940 and it appears also in 1941. An effort to sell the type to Mexico was barred by the Canadian government. CF-BMB cancelled from the register in 1950. Photo by: Rudy Arnold / Smithsonian Institution
