Dear Meremodeller,
I can agree with you, I find the Tamiya IJN Green a good representative of the cockpit green of British fighters, and more importantly to you, Spitfires......................
However could there be an explanation the Inscrutable Japanese manufacturers were the original manufacturers of 'Cockpit Green' and this is how they got the colour so close???
Joking apart, it is what I use, despite what a rivet counter, paint expert, or just an armchair expert says. Remember Col. Tony's saying TLAR = That Looks All Right
Cheers,
Kevin
