XT :
there is in France a specialist of B47 that operated at the ALAT and, after, operated a pretty amount of B47 for crop spraying.
His name is Aimé Fabregat and owend a helico company called "tourraine helicoptères".
I know he was reknown as a specialist for all B47 overhaul & maintenance operations in France and more.
I don't know if he is retired ot not.
