Viscount
Viscount was a motorcycle produced in 1960.
This was a brief revival of the Australian Norvin - a 1953 marriage between a 998cc Vincent V-twin engine and a Norton Featherbed frame, known as the Viscount. It used the wide-line frame, Norton forks and a Manx front hub.
Lack of demand brought the project to an end.
