That is actually a picture of one of my Cortina's and it is a 1964-65 Cortina 2 model 537,one of the first models produced.The first model 527 is pictured below.It is essentially the same it just has the front air box and not the air hose.

As I said before there was many different variations of this model over the years.The base stayed basically the same just adding side chutes on either side (Not on the same model though).
It just makes it easier if everyone knows that there looking out for. Not just a model name.Good luck with your search.You should fine one there is still a few out there to be discovered yet.

Here for a good time,not a long time.
