For readers familiar with Volume I, Volume II is likely to be a surprise. Although the focus of Volume II remains on the most mass-produced high aperture binoculars ever, the 10 x 80 "Flakglas," this book, for the first time, truly offers insight into how the German military and optical industry organized the development, production, and distribution of military optics in general. Using the D.F. 10 x 80 as a reference point, Volume II provides collectors with insights into systems applicable to all types of German optics of WWII.

​

For the first time, a comprehensive taxonomy of German military optics is presented to the collector community, revealing the many intrigues between the military, politics, and the optical industry. It also sheds light on the various logistical systems, including the allocation of serial numbers and detailed descriptions of the different repair systems.

This book is about the Flakglas, but it offers so much more.
