Thanks for all the info guys. I'm not bothered about the masks, and not really that turned on by the PE, as my hands will find it all difficult to manipulate. But, I'll be trying to use the pre-printed instrument panel at least. The main interest is the wing root gun bays, which I know are moulded so that they can be displayed open, and the alternative open position canopy, which eliminates the need for packing out between the fuselage and canopy rail gaps. And of course, for such a (relatively) low price, I just can't resist it!
Soon as this stupid Postal strike is out of the way, I'll be ordering one methinks!
