G-BEHG
Originally bought new by Greenham Plant Hire to replace their previous 206 - G-BCVZ. Both flown by the late Paul Midgley. He had previously flown the 206 for Streeters of Godalming (reg forgotten - grey/red/white scheme, exported to the US I think).
HG then went to Compass Helicopters in Bristol. Company set up by Gilbert Greenall of the brewery family who did his PPL at Mann's and bought a 47G-3B1 (reg forgotten too).
Compass' pilot was a very pleasant ex-crab called Mike something.
No doubt someone will fill the gaps.

They were indeed coachbuilders, I think the then MD was a helicopter fan.
They also owned a 206L11 G-HBUS.
Trouble was, the heli-friendly MD retired/resigned/fired/whatever, and his replacement didn't share the hobby.
Eggs and basket comes to mind.
Same thing happened later in my illustrious career with Unipart and hot-air balloons.
