Thanks Rhys.
May 1970... I think that is one of the earliest pics I have of a driver wearing a full face helmet. Not the sharpest or best of pics unfortunately. Ulf Norinder
Another not so good pic. Part of the problem with having to set the distance before shooting - and it was probably accelerating hard! September 1970
Brands Hatch April 1971, Howden Ganley is still in an open face but the driver behind is wearing a full face.
