Jadgtiger: The Most Powerful Armoured Fighting Vehicle of WWII, volume 1, Technical History, by Andrew Devey, Schiffer Publishing, ISBN:0-7643-0750-9 $50
This is the book you need. 144pages, 170 b/w photos, 60 line drawings. Details the origin, design, construction and assembly of this vehicle. The armour, armaments, engine, transmission, suspension systems, electrical and optical equipment are all covered in detail. Everything you never needed to know about this beast!
Sorry, I don't own it myself, or I would be able to answer your questions. I only have volume two, Operation History. If you need info on that, I'd be happy to help.
