Back in the late fifties, early sixties before Sochiro gave the world the Honda 50, Britain had a load of second division manufacturers knocking out cheap, get to work utility two strokes. Mostly utilising small Villiers engines, names like Norman, DOT, Excelsior, Francis Barnett, James and Ambassador are now almost forgotten by most people. They were all small time players who built up bikes using out sourced components.
Listed as a 1959 - '62 Ambassador tank, check out the A on the badge, I have just scored it for thirty quid. Purely because it looks very much like a Wassell to me and Ambassador were never a big enough concern to make their own tanks so odds are they bought them in.............from Wassell, we'll have to wait and see.
