As a Luftwaffe tunic and tab specialist, I use the following:
"Uniforms and Traditions of the Luftwaffe", Vols 1-3 by Angolia
"Uniforms of the Luftwaffe", vols 1-2 by Brian Davis
"Hermann Goering, From Regiment to Fallschirmpanzerkorps" by Roger Bender
"Air Organizations of the Third Reich: The Luftwaffe", by Roger Bender
"Air Organizations of the Third Reich" by Roger Bender (Despite the same name, they are different books. This is the predecessor to the above listed.)
I have others, yet these are the books I use the most.
Regards
Paul
