Thanks for that schematic Andy, I appreciate you taking the trouble to post it. It ties in to another I had found earlier on the internet, with just minor differences about the cowlings. I had already started painting when yours arrived - patience was never a virtue, I'm afraid - and, as they're both very close, I felt it was OK to progress with my masking. I hope you agree it might fall within the range of 'variation'. I haven't much to report apart from the masking and painting, so I'm padding the post out, with the stages I went through. I should say, that most of the photos have had to be taken with flash, as we haven't seen much of the sun here in the last week - it is July, after all - so the colours are a bit 'colder' than they are in reality.
Pictures 1 2. The aircraft already having an overall coat of RLM 76, I masked off the underside, to avoid bounced or overspray. The fuselage sides were also masked to try as far as possible to conform to the scheme on the photo reference. The mask edge was then prised away to leave an uneven feathered line. I found it easier to work with painters tape for this, as it lifts easier than Tamiya tape.
Picture 3. A slightly transparent coat of RLM 75 was sprayed to give an impression of slight fading. This was a mix of Tamiya acrylics XF 54 Dark Sea Grey and XF 49 Kharki, 3:1, to give a 'mouse grey' tinge.
Pictures 4 5. As the top surface of the wings have hard demarkation lines, I masked these out using Tamiya masking tape. These edges can then be loosened slightly to give a subtle feathered effect. The RLM 75 areas could be filled using the coarser builders tape, not forgetting following the masking through on to the slats, for attaching later.
Pictures 6 7. Finally, the coat of RLM 74 was sprayed. This was a mix of Tamiya XF 63 German Grey and XF 74 Olive Drab, 4:1, to give a slight green tinge to the gray. When the masking tape was removed. i found that the horizontal stabs were done incorrectly, but this was easy to put right, with some local masking and a respray. So now I'll have have a close look to check for any retouching required. The flare on the starboard flap is from photo flash.
So, next stage will be to tackle panel lines and weathering on the underside. More as soon as I have something.
