!948 350 Manx Nortons.

Hi.

I'd like to contact the owners (past or present) of the following 1948 350 Manx Nortons.

Engine/Frame Numbers:

These three machines, which includes my own Manx, were delivered to Chambers Motorcycles in Belfast in 1948. I know that 15940 still exists having photographed it at Jurby during the 2011 MGP (I didn't recognise its significance then), it may have been Swiss or German registered.

Any help please.

Ian.
