Well, there can of course be more than one prototype of a car but in this instance probably not.
It may well be the same car: my puzzle photo shows it as found, before restoration, but your photo probably shows it post-restoration. The registration number is not an original one but what the DVLA likes to call an 'age-related' plate, which to the unitiated might look just like an original plate from an older car but actually looks all wrong to the registration anorak like me!
I can't really see any differences; I'd say it's the same car.
