That's Herb Jefferson on the unbelievable B31 Beeza that nobody could catch. Often wondered who did the engine work, cams etc. Also just noticed looking at that pic how far back he had the footrests mounted. Hagon frames were just around the corner of the calender!
Glad you like them!, pity I was a bit slow chasing the aputure/shutter speed adjustments on the ol' Lieca!
Still more left! cheers.
