Bolkow: Yes, BFYA was part of Julian's stable for almost a decade. She began life as D-HJET before being bought by Ferranti Helicopters in 1978. In 1982 she was told to my godfather's dear friend, the late John Crewdson of Helicopter Hire, who sold her on to Julian in 1986.
From Veritair she went to Sterling (1995) and finally to Alan Mann (the latter being more of a paperwork exercise than a change of ownership).
While with Julian I think she served with the Strathclyde Police and perhaps one or two additional forces.
I have images of her from almost every chapter of her career.
Another ex-Ferranti Bölkow which also chipped-in with some Police work (Sussex) and serviced a number of lighthouses was G-BAFD:
