Quasar demonstrator in the Isle of Man

This is the original Wilson's Quasar demonstrator in the Isle of Man in the late '70s. It was subsequently on display in the Bristol Industrial Museum for several years disguised in beige and brown but has now been restored to its original colours and in November 2015 was put on sale by Verralls.

And see here, on bikeweb, for more information about the bike from Mark Crowson, and some fascinating reminiscences from Royce Creasey about what the machine has been through and survived, including the deliberate riding of it into a ditch for a thoroughly entertaining Quasar promotional film, which can also be viewed on the same page:
