It was given the registration G-CYEI and was painted to represent one of 52 Avro 504K aerobatic trainers used at the American Expeditionary Force No. 3 Instruction Center, Issoudun, France, in 1918. The type was the first introduction to flying for many USAAS pilots and continued in use after WWI

The Avro 504K was the first introduction to flying for many US pilots during WWI. The type proved very capable and was kept in service as one of the USAAS's primary trainers for years afterwards. This rebuilt example is on display at the National Museum of the USAF and painted to represent one of the 52 Avro 504K aerobatic trainers used at the AEF No. 3 Instruction Center, Issoudun, France during 1918.
