This plane was originally built as a T-7 and TOC with the USAAF as 42-2490, later remanufactured as a C-45G and re-serialled as 51-11701 with the USAF from December 1952 to March 1959. In May 1963 a CoA was issued for N9541Z as a C-45H and it passed through various private owners, although between 1986 and 1989 the plane was refurbished and painted into this SAC scheme. From December 1990 the plane became G-BSZC but this was cancelled in August 2016 after being sold in the Czech Republic.
