The character at 613 was Fred Fermor (who actually looked a bit like Fred Flintsone!)
He had a homebuilt sports car on which the perspex windscreen as so badly crazed, he used to drive with his head out of the right hand side to see ahead!
One day he flew a Mk3 'back to the hangar'. There was clear daylight between the wheel and the ground as he went through the hangar doors!
