I enclose a photo of my newly completed Smith Motor Wheel (Milwaukee, USA), 150cc automatic inlet valve, 1916. It runs very well but is a devil of a thing to start due to the 8:1 reduction gearing of the road wheel, mounted direct on the end of the cam shaft. There is a 4-lobed cam on this camshaft. I wonder if there are any examples of this in the UK.
Also recently acquired is a 1950 Victoria 38cc clip-on (German) two-speed, chain drive to a 48T sprocket on the back hub. Its not on the road yet so I cant comment on it. I do not recall seeing one mentioned in Buzzing.
