Hi, just joined your forum after finding the reference to Zenith motorcycles,

I would be interested in any further information from Kestrel or anyone else.

Quoting 'kestrel':
"The Gradua system was designed by Zenith engineer Freddie Barnes, and manufactured for Zenith by the Advance Motor Manufacturing Company in Northampton."

I have never heard of Advance Motor Manufacturing or that Zenith used them, and would be very grateful of any information of references that would increase my knowledge of the Zenith marque.
