One of my goals in real life is to own and fly my own Spit and Stang.
What pilots license do I need? How high can I fly the plane?
From my recollection, you would need the regular private pilots license, plus endorsements for tail-draggers, and for complex aircraft (retractable gear and/or more than 200 horsepower). I believe flight above 18,000 feet, or in any non-visual flight rules conditions, requires an instrument rating as well. I question whether you might be able get the more restricted "recreational" pilots license and still get the extra endorsements to fly these high powered craft.
