The Avro 504L was originally a seaplane - note the added tailfin. This was one of six such aircraft constructed from spares by A.V. Roe at Hamble in 1919. G-EANB sold to Sweden as S-IAA and based in remote Porjus on behalf of a hydropower project. The logo still visible on the fin is associated with this. To S-ABAA and sold to AB Göteborgs Luftdroskor (Gothenburg Air Taxi).
