These walk-around photos were taken at the RAF Museum London in Hendon in 2019. They show a Supermarine Spitfire Mk.Ia, serial X4590, displayed in the markings of 'A' Flight, No. 609 (West Riding) Squadron at RAF Middle Wallop, October 1940 — one of the few surviving Spitfires that genuinely flew in the Battle of Britain. Completed by Supermarine at Woolston in June 1940 and delivered to 609 Squadron in October, X4590 was the regular mount of Pilot Officer S.J. Hill during the closing weeks of the battle. On 21 October 1940 Hill shared in the destruction of a Junkers Ju 88 which crashed at Manor Farm, Milford-on-Sea — the 100th enemy aircraft claimed by No. 609 Squadron, which on that same day became the first RAF squadron to reach that milestone. After its frontline career ended with 609 Squadron, X4590 served with Nos. 66, 303 (Polish) and 57 OTU before being withdrawn and used for training purposes until packed for museum preservation in August 1944. It went on public display for the first time during Battle of Britain Week in September 1954 at Horse Guards Parade in London, and subsequently served as a travelling exhibit through the 1960s. Formally transferred to the RAF Museum on the day of its opening, 15 November 1972, it arrived at Hendon in 1978 and has been on display there ever since.
