Item #41682 : Original period publication. We are pleased to offer a very limited run (30) of this well known book, authored by long time collector Jeff Noll. The subject matter deals with the deciphering of the sometimes confusing, often complicated sequence of numbers and letters which are often found stamped on Imperial German weapons and equipment. Each spiral bound volume is of 198 pages, with English text, illustrations and tables. Each copy is signed by Jeff and numbered. New condition. While they last.
