I have a reprint of the  Baker Manufacturing Company "Monitor" parts manual for the full line of Monitor  Gas Engines. This manual covers from the 1 1/4HP to the 15HP. A few pics of engine parts in the manual. the rest is all parts pages. It is 12 pages. Color front and back. No date on it that I can find. Face stapled and front and back are card stock. It covers the different sizes and all the parts for them. It measures 8 1/2" by 11". A great addition to any collection. P.S. I am working on a super rare monitor instruction manual. email me with questions.
