Because there were so many kits, it's impossible to know now whether a Climax-powered series 1 is original, but the odds are heavily against it (despite that fact, the would-be sellers of such cars all believe theirs are original!). I restored #414, which would have been made in Hornsey and originally had floor-mounted pedals - yet the chassis plate is a later one (it says "Made in Cheshunt") and the car has swing pedals. They didn't even USE chassis plates on the first batch - Colin Chapman used a bed frame as the welding and assembly jig!
This car and most others like it today use BMC power (948cc, MG Midget / AH Sprite). Almost all series 1 7s have cycle fenders. There were a few late 1959 series ones called "Seven Americas" that used 948 BMC engines and had beautiful aluminum clamshell fenders hand made by Williams and Pritchard. These were the prototypes for the 'glass-fendered cars starting with series 2.
Later "supers" used either Climax or Cosworth power, and a variety of "lesser" engines power the not-so-super 7s. There's even a modern limb of the family tree that uses Mazda Wankels, Mike.
