No Nazis here there all in the British Royal family from what I see !!!!!! in other Balkan countries there are many Hitler saluting swastika wearing idiots.
Remember that 'Triumph' was originally a German make .
If you've just got an engine I would offer it for sale in the Triumph Owners' Club, In Old Bike Mart or to the National M/C Museum. There can't be many people looking for a motor for a restoration - can there ??
