They're coming along nicely, Martin.  I think the Pfalz D.III/a are the best looking aircraft of the war- very sleek and business-like- so I'll enjoy watching your build progress.

Cheers.

Beautiful Pfalz, Martin.  I'm sorry but I have to ask...are the white speckles supposed
to be there?  I've never seen that before.  If so, it is really quite a neat paint scheme. :)

Post by: Ernie on March 04, 2014, 10:22:23 PM
Oh that explains it! Thanks, Martin.  I saw a paint scheme, an Albatros, I think, with
little white stars on a black background and I thought this was a variation on that theme.
  How can you not like basic black? ;)  :)

Hello Martin:

This is coming along nicely.  I like the schemes you have chosen.  I am doing Berthold's DIII.a using the WNW kit and decals.  I did the DIII.a. in Degelows scheme with the white tail feathers and lozenge wings.  Yours is turning out nicley and I look forward to seeing you progress to completion.

Thank you Mark. Like a picture are the wings of Degelows aircraft black.
Martin

Hi Martin:

Degelow flew with a couple of squadrons.  The one you are doing is simliar to the one I did.  The markings you are doing are when he was with Jasta 7 and the lower wing was the early type, the other was when he was with Jasta 40, (Pheon sheet 32025)  the wings had lozenge, the lower had the rounded wing tips and a totally white tail area to include the tail plane and elevator.  I like the way this is turningout.

Best
