Many thanks for all of those replies, which has exceeded my expectations.
With regard to the bike I would like as my first Norton, it would need to be a left hand shifter, so that’s limited the choices considerably already.
As for my skill set, I’m not confident to do much other than the very basics, so it would need to be a good one to start with. I’m not necessarily after a minter, so a good honest bike, mechanically sound, but showing its age, patina and character would be fine. Having said that if a gem did turn up I’d be prepared to spend more.
Looking on line I see the prices for the later Commando 850 ranging from £6,000 to £12,000, so I need to get myself informed before going to view any in the new year.
Unfortunately I don’t know any other Norton owners locally, I am situated in Cornwall.
