Al,
I think I would try Warbirdcolors or Vangard for the new acrylic paints. The color scheme is one that was standard post war and Korean war for both Canada and Britain naval planes, being extra dark sea gray over sky. There are plenty of sources for the correct color, I just think this new acrylic paint is the best.... Of course, that's just my opinion, I could be wrong.

Thanks again for the HEADS-UP on the Spit!!!!
