in june i will stay two weeks in southern england with my family. i'd like to integrate some parts and bits shopping for my 16h. i would be very happy if you could provide some addresses of dealers or experts.
Martin, as you'll have found out, there are no 'one-stop-shops' for Nortons of this age and most of the 'old' dealers have gone...added to which, most of the military bike owning community will be in Normandy.
There is little point in calling in on Russell Motors in South London unannounced but if you talk to them first, you may be able to save some postage costs by collecting.
It's not a busy time for autojumbles but there is one in Kent at the end of June (I haven't been so don't know how big it is)
The Banbury Run is 8th June (It's not really down south but well worth a vist and has a jumble).
If you want to keep the family happy then the New Forest is nice and would let you visit Sammy Miller's museum and the Beaulieu collection.
