Grob Driver:
As Ozplane says, Gordon's a nice fellow. But it would help if you explained your motives. Are you trying to scrounge a flight?
I'm sure that some people who have already posted could put you in touch with Gordon, but are reluctant to say so without knowing your reasons.
Not being awkward, just expressing a feeling.
Drop him a line via his address on G-INFO, that might be your best bet.
Navion, sometimes called a poor man's Mustang. Gordon's is a lovely example, very high workmanship.
Cheers
