Disclaimer: I know next to nothing about 1960s cars :-D Little is known about this concept, although the original Sunbeam Tiger is a popular classic V8 sports car that was designed by racing driver Carroll Shelby. Maybe there's a connection? The rest of the rear looks nothing like it but the upper rear quarter-panel has a distinct notch shared by hardtops put on the AC Cobra (a.k.a. the Shelby Cobra) and the front of the car has Cobra-like "snout" and fenders. This is total guesswork that smarter people could probably destroy in a heartbeat, but could it be a camouflaged prototype? The Cobra was prototyped (and being built at Thames Ditton) in early 1962 – https://www.supercars.net/blog/1962-ac-shelby-cobra-prototype/ https://www.supercars.net/blog/1962-ac-shelby-cobra-prototyp... – and the arches look oddly rough/plain in that photo. Could it be a prototype with the flared arches removed and a hardtop stuck on?
