These walk-around photos were taken at Flygvapenmuseum at Malmen outside Linköping in 2017, 2019 and 2022. They show a Supermarine Spitfire PR Mk XIX, designated S 31 in Swedish service, coded F 11-51 in the markings of F 11 Nyköping — one of the most important aircraft in the museum's collection, and a representative of one of the least-known chapters of Spitfire history. In 1948 Sweden purchased 50 unarmed Spitfire PR Mk XIXs for the reconnaissance role, basing them exclusively at F 11 in Nyköping as the S 31. Powered by a Rolls-Royce Griffon engine with a five-bladed propeller, they were Sweden's fastest piston-engined aircraft and served until 1955 when the S 29C Tunnan took over. During their service the S 31s undertook some of the most sensitive reconnaissance missions of the early Cold War, including clandestine overflights along the Soviet-controlled Baltic coastline. All 50 were subsequently scrapped, leaving no original Swedish example. The aircraft displayed here is therefore a reconstruction — built on a genuine Spitfire PR Mk XIX airframe originally delivered to the RAF as PM627 in 1945, later sold to the Indian Air Force as HS964, and acquired by Flygvapenmuseum in 1982 through aircraft trades and donations. It was then restored by volunteers from Östergötlands Flyghistoriska Sällskap over thousands of hours and painted in authentic S 31 colours to represent the type in Swedish service.
