This is a 

Vintage Scalextric Mini 1275 GT, C122, with chequered roof. Produced during the 70s, with square Clubman front nose structure.

Been in the loft for years, well boxed. Part of a collection of cars and other Scalextric equipment which belonged to my son.  Well looked after and original, but hasn't recently been tested.

Check out my other items I will be listing shortly.
