Nicely done Andy. As for the gun sight, although the gyro sight (on which the American K-14 was based) had been in RAF service in the ETO since late 1943, most Spit VIII pics I've seen in SEAC appear to have the standard reflector sight. The film footage mentioned earlier also shows the reflector sight.
Paul, the internal windscreen frames were normally the same Cockpit Grey Green as the rest of the cockpit, although the frame for the internal armoured windscreen was sometimes black, presumably to reduce reflection.
