That Sunbeam is gorgeous.
My cousin who lives in Dearham (not that far from you) has one in his collection last time I called in he had just bought a VN2000 asking if I wanted a run out on it I declined but took the Sunbeam out, great bike but it had the flat road tyres which meant it did not go round bends without a fight.
He has had it over on the IOM a few times, also has a Triumph Tiger Honda Goldwing in Yellow with a matching trailer and various old project bikes.
I have a special love for the AJS as my dad had one.
