Thanks Edgar! It's good to know that I wasn't totally imagining the dark color on the armor plate in some early Spitfires. It would seem from all that I read here that by August 1940 the armor was most likely painted in the same interior grey-green as the rest of the cockpit. I am in the process of coverting a Tamiya MK.Vb back to a MK.I (cannon), R6776 QV*H, as flown by Flt. Sgt. George Unwin during August 1940 and the armor plate will be interior grey-green. Happy Modeling, John R.
