Greetings!
Just recently got the game, and needless to say, I'm impressed. You guys did a lot of work. You beat me to doing some of the same things.
I just may adjust the rules a little for different theatres such as the ETO (European Theater of Operation) and the PTO (Pacific . . . ) by playing them separately, to represent a little more historical accuracy (and how is that possible you may ask?). If you want to use the whole world which could've or did go to war, it is so hard to represent elements of the conflict on the same scale. For instance, land units in the ETO fit at the corps level. In the PTO, land units were usually at the division level if I'm not mistaken. You guys did so well. Larry Harris would be/is proud of you, I hope.
BUT, on to the point: I've found White Ensign Models in England to have really good resin 1/700 scale multi-engined aircraft and 1/500 scale single engined aircraft.
They really fit well with A&A, World at War, and especially, WW2: The Struggle . . . . They are discontinuing their lines though.
They still have the molds and do make new models if there is enough interest in producing them.
I got some B-24's, Ju-52's and SM-84's that look like they were part of the original (sic) games. I got a couple of 1/500 SBD's (for USMC Aviation) and they fit!
If you're interested, drop them a line. I hope to be at GenCon-Indy to let those present take a gander.
Enden.
