I have 28 of the 31 Disc/Book set of Weapons of War: A History of Military Tools and Machines. These are all still unopened and in the original shrink wrap. I'm not sure what happened to the missing 3 discs, but I'll keep looking for them. If I can't find them, they can be purchased from the distributor if you want to finish off the set. I'll leave an update with any new information. *Update 1/5/11 I still can't find the missing volumes, but I emailed IMP and they will sell those separately if you want them.* Weapons of War - discover a history of military tools and machines!
