I'm looking at a LHD 3 wheeled Isetta, sliding window, cow lifter bumpers on front and chrome rear bumper with overriders, seven inch headlamps and reputed to have been first registered in 1960. Is this defiantly a Brighton built car , I heard some story about unsold German built cars coming back from Canada and being converted to three wheels in Brighton and sold in the UK. Is it possible to establish facts from the chassis number? Any help appreciated.
