Got the mottle and yellow nose done. Checking the available photos against the profiles, it's very evident that there were two aircraft, with slightly different fuselage spine cammo patterns, and different shaped Kommandeur winkels. I've gone with the one with light mottle, and the RLM 71 extending down the angle of the rear cockpit.
PICS 1 and 2 Show the modified spine pattern, the light mottle of RLM 02 and the yellow nose.
PIC 3. The rudder as provided in the kit, with ribs as a big as the bars on a farm gate, and some light flash.
PIC 4. After being filed and sanded, but before polishing. Keeping just a light impression of the ribs.
PIC 5. After painting, using a mix of Humbrol No. 30 Trainer Yellow (enamel), with a touch of red added. After a gloss coat of enamel clear varnish, this should look even smoother, and more like the real thing.
Next step is some detail painting and very light panel work, then clear gloss coats. Whilst the latter is hardening, work can be done on the undercart and prop.
Thanks again for your continued interest and I'll post some more pics soon.
