Im trying to trace the previous owner(s) / mechanic(s)who have worked on a 1950s George Cohen ES2 (reg YWG661)

Good evening.

After the MotoGP on ITV4 Monday evening there was one of Henry Cole's programmes, Junk & Disorderly, featuring a Norton single with an electric start.

I am nearing the end of restoring a '47 Inter model 30.  The only rubber seals for the primary case that I seem to be able to find are the ones supplied by the club, RGM and Andover Norton, measuring approximately 9mm thick and 24 mm wide.

So since I finished my 38 model 18 I fancied a full restoration this time So was very lucky to stumble across this one and being literally just down the road from me! You never know what's lurking in garden shed.

Hi 
My 1928 CS1 engine is complete, but there is a lot of backlash between the vertical shaft spline and the bottom bevel. It seems like the wear is in the bottom bevel where the spline runs. The shaft splines look good.

Does anyone know for sure when the camshafts marked QLL (both inlet and exhaust) were used?
Were they always the same for M50, ES2 and 19S models in any given year?
