Thanks to all commentators.

I think this will be a fun subject, and there are several good photos of the bird in the OTF article noted above. Unfortunately, no photos exist of the top of the upper wing according to the article.
Bud, so glad you're doing the same in smaller scale!

Maybe we can pool information, particularly on the difference (if any) between the Nie. 27c1 and the Nie. 27 E.1. What version is your Karaya kit? I have been unable to find much technical information on the E.1 version. Maybe it was just a designator for a trainer version with some upgraded mechanical systems or a different engine. I'm not going to worry about it too much for now, since the versions appear to be rather identical on the exterior, but maybe I'll pose the question over at the Aerodrome site and let those guys chew on it awhile.
The one thing we won't likely find much on is the "American shield" and white wing markings on the upper wing surface. What's your take on that? I did a google search for Liberty Bond posters, since QR referenced them in describing the paint scheme, but there really wasn't anything that jumped out at me. I thought about the later Army Air Corps winged cockade, but that has yellow wings, and QR definately drew a distinction between the cockades on the upper wing and the "American shield." The Great Seal of the U.S., on the back of the current $1 bill was my leading candidate for awhile, since it has a shield with stars and stripes and the Eagle wings, but my research has indicated that the Great Seal was not used on the back of U.S. paper currency from 1914-1918.

I suspect I'll end up doing some sort of shield shape with a stars and stripes motif, centered on the top wing, with the white wings extending outwards toward the cockades. I'll keep you posted if I come up with anything else. The good news is that neither of us can really be wrong!

I won't be starting actual construction of this project (assuming I can restrain myself) until the Lloyd is finished, so probably inj March sometime.
Regards,
Bob
