I must admit that I'm a little confused now... I searched in my docs and I found 2 versions: cockpit overall RAF interior green (grey-green) until September 1943 and then the rear part of it was aluminium dope (standard paint treatment/mod.787 on 13 September 1943, and the other version: cockpit RAF interior green (grey-green) with the rear part unpainted and then overall grey-green from early 1944...le_steph40 seems to have some info about that given he told another builder the bare aluminum started with the V. I'm going with the bare aluminum unless someone proves me wrong.
