FastFred,
Seeley920has answered your parts question already.
I am not "Andover Norton". That is a team of people dedicated to quality Genuine Norton parts which includes myself.
I am but the owner of the company with my own, private collection of Nortons including some Commandos. One of them is my daily transport (weather allowing), and all are my hobby and ridden as much as possible, often on racetracks. I guess followers of our homepage have seen far too much of my beloved "Signal Orange Shortstroke Roadster" by now!
I have restored that machine- and a few others over the years- myself, so know from personal experience how our stuff fits and lasts, and where our parts portfolio is not as complete as I think it should be. So, more often than not, the introduction of new parts has something to do with the latest project I have on my private workbench. Shortly to be available- Manx clutches. Guess why....
