I have a beautiful reprint of the 1914? Witte Iron Works Gas Engine Instruction and parts manual. This is before they changed their name to engine Co. Front and back are heavy duty card stock. It covers engines from 1 1/2hp to 11 hp. Has alot of info on the care and operation of the Witte engine broken down into 42 different paragraphs. Everything you need to know as an owner to operate and take care of a Witte engine. it  is b/w, 8 1/2"x 11" and 20 pages.  see pics before buying. A great addition to any collection.
