Still here Graeme
But was just about to turn the pc off when I thought I'd have one last look. David's photo is on Minijets website:
The Minijets Website: Caproni A21J Calif where you'll see it referred to as a A-21J modified by Lockheed. I did a bit more investiagation and it is the only one and was purely experimental. Not sure if it should be classified as American or Italian?
Anyway take a look at the link and I'll leave you confirm or not - as I said it will have to be OH anyway.
Have a good day mate - cheers
