Avro 504N - American Users

The Avro 504N was an upgraded version of the previous 504K and it was used by the next American users:

• Argentina: Apparently the Argentinean Army Air Service bought at least one of them to test it. Further details are unfortunately, unknown.
• Brazil: The Brazilian Navy's Air Service had some of them under service, most probably replacing the old 504Ks. However as we couldn't find further information, the drawing is speculative.
• Canada: The Royal Canadian Air Force had some 504N in service. Further details are unknown.
• Chile: Apparently it was also used by the Chilean Army Air Service, however any further detail is unknown, so it should be considered as speculative.
