Just got off the phone to Don Greig and no, it's not a runner, when asked, Don's remark was that " I'm not that clever" I would sorta , kinda, disagree with that, because of the following.
Don built , from scratch, the frame, forks, tanks, seat, mudguards, sprockets, dummy clutch, petrol taps, twistgrip , dummy JAP timing cover, exhaust pipe etc. The wheels are off a treadly and the barrel is a Victa lawnmower barrel with the exhaust port moved up higher . It took him seven months to build, scaled from photos of full size JAPs,halfway through his son presented him with a small lathe which made things a bit easier and Don built it as a shed wall decoration, it now resides on the coffee table in his sun room.
No mean photographer himself, Don has some old short circuit shots that he is sending up to me so I can post them for him on Slides CDT Images thread.
