Guys... thanks a million for the heads up and feedback!
Personally I never trust kit painting instructions anyway, so always try to find original photographs if possible.
I definitely want to stick to this paintscheme, so have just ordered a set of Xtradecal markings for 1H+GP in Wojtek's post #14.
Also won a bid on a CMK He 111H-6 cockpit set today, which will save the -P set for when I do a Hungarian bird...
Wojtku, looking at your pic in post #16, I think the lighter elevator colour is exhaust staining from the engines. As for the theatre markings, it looks as though they were whitewashed, like the tyres. This may explain the tonal difference, as they would not be as hardwearing as production paints, and fade out quicker. Also, the G in 1H+GP is Yellow, and *seems to be* darker than the cowlings and rudder. Will check Kenneth Merrick's book to see what he says on MTO paintschemes.
Don - If you don't need them yourself, I would gladly take you up on that offer please! Please let me know if there's anything I can trade you in return.
Cheers again guys, all much appreciated!
