Got a new one the other day:
X-Planes of the German Luftwaffe, Prototypes 1930 - 1945
Pretty well covers all of the German air industry from Arado to Zepplin. Doesn't show the production models, of course, but only the prototypes that led to production (or never did). It also gives data on the various prototypes that were pressed into service even if there wasn't a production version (example: Bf161 and 162 Schnellbomber prototypes later were used in the Me163 testing program)
The book gives good data about disposition and Werknummers.
Hardbound, 288 pages loaded with archive photos (at least one per page) Author is Manfred Griehl and it's printed by Frontline Books [ISBN: 184832555-X]
