So far as I can find out Maxwell painted six greens: Maxwell, Dark, Brewster, Royal, Wedgewood, and Calumet. Different years had different greens. The 1911 GA for instance was Brewster. I found a nice Brewster. Painted out, the car "looks right". Th paint no is acrylic enamel, PPG #DAR42850. Anyone else have any wisdom on kinds of greens (or reds?, or blues?)
