So, it's a kit?
Yes.
Falcon was founded by Peter Pellandine in the mid fifties (isn't he a member on this forum or is that his son?) originally to offer a sporty body on the Austin 7 chassis.
This Mk3 was introduced to use the Ford 7'6" chassis and its usual engines (which means the old Ford Pop and the 1172 cc sidevalve motor) but later was offered with its own bespoke chassis.
It was certainly one of the better kits.
The body was used for that DKW but of course that's a different car.
I posted the Convertible because a) it's so pretty and b) it was much rarer than the Coupe; in fact I'm not sure any number were ever made. Most Mk3's/Caribbeans I've ever seen pictured are Coupes. Here's a picture of one:
