Registered 18 August 1919. One of 12 conversions from war-surplus Avro 504Ks by A.V.Roe & Co.Ltd., to whom it was originally registered. G-EAKM's fuselage was 9" wider, so that four passengers could be carried in the rear cockpit. Although completed mid-1919, it was placed in store until sold to Surrey Flying Services, to whom it was registered 30 July 1925. While airborne from Croydon -4 July 1928, it crashed at Taplow, Bucks., injuring all three occupants. Cancelled January 1929.

Registered 25th Nov.1925. Sold to Sir Alan Cobham and registered to his National Aviation Displays Ltd on 27th Nov.1933. Converted to an in-flight tanker in 1934 and flew out to Hal Far, Malta later that year to refuel Sir Alan's Airspeed Courier G-ABXN on its attempted non-stop flight to India. There are conflicting reports as to whether it did carry out the proposed refuelling over the Mediterranean or not but the Courier suffered a throttle problem, which necessitated Cobham forced-landing on Malta. That flight was abandoned and W.10 G-EBMR was sold locally for scrap. Cancelled Nov.1934.
