OK, I'm back now and have access to my files.
I didn't think I recognised the name 'Falcon' in relation to this puzzle, but I wanted to check to be sure.
And sure enough, that isn't the name I have, amazingly!
It is obviously the same car, made by the same company, even using the same picture, but the model name I have for it is different; whether it came before Falcon and they decided to rename it Falcon, or whether it came later I don't know.
But I'm still looking for the name under which the puzzle photo went, and it's an Allied Something Else!
Locked therefore for you to give me the other name, the one I'm looking for.
