I think the DDN photos have been examined as closely as possible. The office photo from the film is tiny and just shows the cockpit area and a bit of the upper wing. The Wannamaker photo is interesting but very poor quality. There are several good quality photos of the lozenged OAW machine and the late Fokker BMW powered one. Glenn Merrill, I think, believed there was a 4th D.VII. One problem is that the "LO!" being hand painted looks a bit different on each side.

I agree about the photos drew. Dr. Merrill did some "Speculation" about the OAW upper wing on Udets DVII F. He felt it was/ could have been used because it "Might Have" had some special marking that Udet wanted to keep such as a Large U or Lo on the upper surface. Pretty thin as there is no evidence to prove or disprove. My guess is that a replacement was required and an OAW wing was available.
Back to DDN I guess I should give my "Preferences" :
Manufacturer: Still debating between the Early Fokker built and Early OAW.
Red and white stripes on both surfaces of the wing ( Like Kirchsteins DR1). Red to be different.
Red Fuselage with black nose. Udet had just initiated the black nose squadron marking so I "FEEL" he would have proudly displayed the Unit Marking.
No white stripes or entire turtle deck . No proof of course and Just My Opinion

In this case, I think lack of definitive proof benefits the 1/32 modeler: one can build one of Udet's from either of two WnW kits (or even the D.BII(Alb) if you have the nose bits from another kit)!
In my case, I'd like to do a 1/32 series of Udet's machines from his Eindecker on.

Rob, you are entirely correct! The lack of proof does give us a lot of leeway as to which kit/s to use. Although only a couple of handfuls of members have voted it is interesting in that the results so far are sort of surprising to me. Close but not exactly as I suspected they would be.
