Well some god news, I was able to speed up my paint drying by using an old "paint dryer" actually a food dehydrator designed to make beef jerkey, has a low dry heat that is safe on styrene plastic (but don't try it on resin, I have had some problems with that!) and applied the white cross fields in the correct position as verified by a photo that I scanned, reduced to same size as the 1/48 scale kit and applied tape while holding the scanned picture right next to the fuselage.
Also a picture of the upper wing with correct Eiserne Kreuze from an old Americal Gryphon decal sheet.
Last but not least, a photo of the 2 cowls, the F.1 in olive with white face decal applied, and the Funfendecker in chrome yellow with white face hand painted.
Also converted photos to greyscale images and this will let you compare them to BW photos. The yellow definately looks light, not sure about the ortho film used on the originals but using modern greyscale I say the yellow cowl definately does not match any known photos of Voss's aircraft.
