Hi Mark and the other members, I can tell you all right now that you can get information on the book club at http://www.militarybookclub.com
A search for the title or my name should bring up the book.
As to the OOB details, they are simply lists of the corps with directly subordinate units (signal, heavy tank, etc.), followed by lists of divisions in which the division is sublisted into separate regiments and battalions. The commanders for the corps and divisions are given by name, rank, and date in position. Below this, I simply list known separate regiments and battalions, without additional information (since this was supposed to be introductory, we had to draw a line somewhere).
The weapons section has organigrams, and I believe it lists the numbers and sorts of weapons found in several typical "types" of divisions and their sub-units (for example, in a 1944 model Panzer Division with a battalion each of PzIV and Panther in the Panzer Regiment, and with one SPW PG battalion). I contributed raw data to Aegis, who supplemented it with tables of organization and strength returns they located in the National Archives. They then edited this into a (hopefully) seamless whole, and created the organigrams. I only saw one sample organigram, to proof the style, so this is the section which changed the most from my basic notes to published form, and I am unable to comment further (yet).
I can state now that NO feldpost # are found, but I believe personnel strength is included. You won't find the common clumsy mistakes of assuming all Panzergrenadiere rode in SPW, or that every division had Tigers. Aegis wanted this section to be a resource so that those unfamiliar with the Waffen-SS could check, for example, precisely how many batteries of self-propelled artillery were actually found in a so-called "Panzer-Artillerie Regiment."
I'm editing this later on, to add one more addition, which was only discovered months after the book was finished. John Moore's Waffen-SS officer CD has made public the information that Hans Havik was born in Groningen, the Netherlands. This need not be important, as other Knight's Cross winners were German citizens, but were born in neighboring countries while their family was engaged in business, or similar activities (for example, Karl Keck and Emil Seibold were both born in Switzerland, but were Reichsdeutsche). However, Yvo Janssens from http://www.soldbuch.com
investigated records in Groningen, located Havik's widow (no date of death given yet), and established that Havik was indeed a Dutchman. Thus the previous assetions that there were three Dutch Knight's Cross winners is incorrect, there were at least four. (The nationality of Karl Picus remains to be determined. He was born in Germany, but attended the 1. Lehrgang für germanische Offiziere at the SS-JS Bad Tölz, which indicates that he was not a Reichsdeutsche, and had leadership experience with a foreign army).
