After a bit of ferreting around the recesses of the interweb, and my car mag collection, it's the stimson mini bug 2 prototype (the rear 'spoiler' is different from the mk1's optional roll hoop.)
The woman is Liz Smith, the wife of Stimson’s business partner Ian Smith who drove the prototype to Monaco where journalist David Benson took it over for a report, and then crashed it before Jackie Stewart had a chance to drive it around the GP circuit!
The moulds have passed through at least 6 businesses' hands, and are mostly still extant, however that particular car was written off in May 1970 before the moulds (and presumably chassis jigs) passed on to barrian, fauchan, nouveau, evans, minimotors and others (Dutch, Swiss) got their hands on the moulds or copies!
