"Norton website". The Norton company closed in the UK in 1976. The company reopened in 1995 in Portland, Oregon, United States, manufacturing replacement parts and eventually new Norton models.

"Vincent Motors". In 1928, Phil Vincent bought HRD and changed the name to Vincent HRD. In 1949, it was renamed Vincent. Production of Vincent stopped in 1955. In 1994, Bernard Li acquired the rights to the Vincent trademark, and in 1996 formed Vincent Motors, USA, which made five prototype motorcycles in 2002. The engine used in these motorcycles has since gone out of production and Li has since died. It is therefore not likely that series production will begin.
