Glenn,
Certainly turned out as a great build. I'll be referring to this since I need to fill in between GB-50 and GB-51. I have the same kit and your 'discoveries' will certainly make my build easier. I will be doing the stock kit markings for the No. 87 Sq RAF 1942. I kind of like the diversion in colors in that this scheme calls for a flat black belly. It will complement my two-tone belly Spitfire Mk.Ia.
Just curious? The interior, you chose a sliver/green combo, instead of the instructions (usually not always close) solid green?
