Hi warbirdmustang,
Welcome to the forum! The best collection for documentation is probably in the books produced by Albatros Productions. They are the ones who print the Windsock International magazines and Windsock Datafiles, Datafile Specials and the special Anthologies. They have a nice bit of stuff on the Albatros D.III that should answer any questions you have about superdetailing that model.
Byrd Aviation Books carries all of their specials--give them a call, I've always been satisfied with their service.
Please show us some pics of your project when you've got it framed up!
Lyle
