Having rolled off the Castle Bromwich production line, SL633 was delivered to the RAF in June 1945 before being moved to RAF Manston in August 45 and re-assigned to No 312 Sqn, Czech Fighter Wing with the code letters DU-K. SL633 became one of the Spitfires that were flown to Plana, Czechoslovakia and transferred to the Czech Air Force serving with No 2 Czech Fighter Wing. By February 1946, SL633 was carrying Czech National Markings along with the fuselage code of JT-10 and serving with the 4th Air Regiment and also the Military Air Academy. Following a crash at Ceske Budejovice in May 48, SL633 was soon repaired and in October 48 was crated, along with the rest of the surviving Spitfires, having been sold to Israel.

        SL633 arrived in Haifa in February 1949 and converted to a FRIXe with the serial number of 20-42. It served with No 101, 107, & 105 Squadrons IAF. Following a belly landing in 1954, it was repaired and refurbished before being sold on to the Burmese Air Force with a new registration of UB-425.

        In 1984 UB-425 was still in existence although it was mounted on a pole in the ground of the Royal Palace with locally made engine cowlings and a tail unit from a Harvard. UB-425 was rediscovered in storage in 1999 although it had been given a new identity of UB-424 and was sold to a collector in the USA.

        In 2006 it was registered as N94141 and moved to Historic Flying Limited, Duxford, for long term restoration. In 2007 it was allocated a UK registration of G-CZAF and registered to HFL. Unfortunately never flown in the UK, SL633 in its Czech markings was crated to the USA where it is now part of John Session’s Historic Flight Foundation, Everett Paine Field, WA. With its new civilian registration of N633VS, SL633 flew for the first time on Friday 15th October 2010 with Kerry Edwards at the controls.
