Hi 2Donkeys.
So that's what happened to GBMSZ, the reg was changed to protect the innocent! I remember SZ as a really good performer when I used to ferry her back and forward to Biggin Hill. At the time she was operated by Luton flight training, but owned by Falcon flying services. Once, when doing a Luton-Liverpool, we got formated on by a Belgian registered PA28 who was lost with radio failure and led him into GP. Looking at the other log book notes all the flights I had in SZ seemed to be good ones. Ah! The rose tinted glasses of nostalgia!
