Identified by the cobra emblem as being from 92 Sqn and in a special colour scheme commemorating 75 years since the formation of the squadron at London Colney on September 1st 1917 when they flew Spads, Pups, Avro 504's and SE5A's. This same squadron provided the RAF's aerobatic display team the Blue Diamonds in the late 50's, early 60,s from their base at Middleton St George (now Teeside Airport) and this may explain the choice of colour. Seen at RAF Leeming Country Fair and Air Show in 1992.
