I know Kora produces prop logo sheets. Is that the decal brand you were talking about?
I honestly don't remember -- I don't build 1/72 so when they were news awhile ago I didn't pay much attention.
PS I think RB is correct, the top prop is a Heine, Niendorfs are a little bit more slender looking, and the contour has straight lines when seen head on. The middle one I'll take his word for, he's more of an expert than I.
Oh, the WS Datafiles 151 & 152 Albatros D.V / D.Va at war have prop drawings included with the aircraft profiles.
Like I said, you've scratched the surface, there is a ton of information out there to explore, and also many vague areas where the information is lost or remains buried. WWI modeling is like that...
Towards the beginning of my long 1/32 Albatros build log I list some references which you may find useful ... I've tried to keep it updated.
Cheers
