The Skysport Bulldog ... has a military look and feel, but it is not really a warbird, despite the paint scheme. Stearmen and Chipmunks are not warbirds either
This is at least debateable. I refer my learned friend to Martin Caiden's excellent discussion on this issue in his book
Ragwings and Heavy Iron: the Agony and the Ecstasy of Flying History's Greatest Warbirds (1984).
