How do they compare with the scale drawings in the Taube datafile? In every case, these DF drawings seem to be better and based on better sources than the Baubeschreibung, though in almost every model I've build from DF, I've been able to find errors in those drawings as well. Sometimes they are simple drafting errors (such as a line not being carried through) but other times the curves might not match reality. But in terms of general outline, I tend to trust the DF drawings over most other sources.

For example, the DF drawings of the Albatros CI appear to be for the most part tracings of the original 1917 description that appeared in l'Aerophile. By comparison the CI Baubeschreibung is crude and seriously off in the nose area.
