Hi X, I picked it up on the network this morning. G-INFO has it as de-registered as transferred to Russia 19 July 2018 and is c/n 343 ex Portuguese Air Force
So while the transponder gives the details of the previous owner it is not G-BMFG and as far as I am aware should be registered RA-***** Between 9/2/2018 and 19/7/2018 it was registered to Vadim Drozdov, Khabarovsk, Russia befire being de-registered on 19th Jult 2018
