In 1920 Denmark bought six Avro 504Ks and five years later took delivery of one 504N, the two-seater trainer version with a bigger engine and stronger undercarriage. Three more 504Ns were built under licence by L.B.I. at the Naval shipyard in Copenhagen and two of the originally delivered 504Ks were also later modified into the N-version. The Danish Avro 504s served at the Naval bases in Ringsted and Avedoere. This is one of the three 504Ns built by L.B.I. and is on display with its original Armstrong Siddeley Lynx radial engine.

First flown in 1913, the Avro 504 had a very long life for an aircraft of its era. The modernized 504N, with a radial engine and a new undercarriage, appeared in 1925 and was a standard trainer in the RAF until 1933. This airframe was one of three built by the Danish Orlogsvaerftet (Naval Yard).
