Volume 1 covers mainly the evolution of the Luftwaffe through it's uniforms and insignia. Very detailed on the actual uniform components, basics on waffenfarbe, and basic insignia. I think that Volume 1 can still be had for under two dollars if you really look. Volume two focuses on the various Officials and Admin organizations and insignia. Also, Hermann Goring Division and Fallshirmjager Corps is covered in the same regard. Volume 2 is very spendy. I felt that I did well finding mine for 300 dollars on Ebay. I have seen private book companies offer it for over 700 dollars. Volume 3 covers the LW Field Divisions, Female Auxilaries, Band and Drum Corps, and others. This one can typically be found for well under 200 dollars as well. In my experience, Ebay is the best place to get these. Paul
