QTG asked about HB-XFD. This aircraft was originally leased from it's Swiss owner. It had a leather, executive interior and an avionics suite, the like of which the Bond Pilots had never seen !! Which was OK except spares were not readily available. It was of course a Bo105C and was bought by Bond in Aug 1981. It was modified to CAA Specification (D Model) and became G-BGWP as a 105DB, it was never modified to DBS standard. It eventually ended up at PAS as G-PASA and was withdrawn from use in April 1993.
Hope this helps. Sq
