They both look to be Vanwall Grand Prix cars, the 1:1 were built in Great Britain be a chap named Tony Vanderwell I believe. Stirling Moss, Tony Brooks were some of the drivers back in the 1950's.
The appear to be in the 1/32 scale range.
ps:the drivers sit way too far out of the cockpit, thehelemtes should be a little bit above the headrest for amore scale appearance.
