Avro 504K, RAF (Serial No. H9555), one of several included in the Imperial Gift of aircraft to Canada, it later became G-CYFG with the Canadian Air Board. Canada Aviation and Space Museum, Ottawa, Ontario

This Avro 504K was manufactured in 1918 by A.V. Roe and Company Limited (Avro) in the United Kingdom. It passed through the hands of several American owners, including James H. "Cole" Palen of Rhinebeck, New York, who purchased it from the Roosevelt Field Historical Aviation Museum in 1951 and used it in flying exhibitions. The RCAF purchased the aircraft from Palen in 1961 and later restored it. It was used in RCAF air demonstrations in 1967 before it was retired to the RCAF's historic aircraft collection. Transferred to the Museum in 1968, it is one of several rotary-engine aircraft in the collection. (CA&SM)
