RAF Directional Indicator , Mk1A

These instruments were fitted in the blind flying panel of all RAF and Fleet Air Arm WW11 aircraft and were designed to enable the pilot to plot a stable directional reference for accurate course steering. The instrument would be synchronised with the main compass before take off and required a venturi to work. The Mk1A entered service in 1940/1941 and remained in production until the 1950’s. This one carries the RAF stores reference number 6A/1298, a broad arrow and a further number 2191/40. An additional plaque has been fitted indicating a VPI filer has been fitted at some stage. It also carries a label issued by the Royal navy showing it had been reconditioned in 1955 and tested again in 1958. This direction indicator is in good issued condition but on offer as a collectable only and would be perfect for a replica Spitfire instrument panel project. Measures 4.5” x4.5” in front plate (12 cm x 12 cm)and is 5.5” deep (14 cm)
