I have a beautiful color reprint of the 1913 John Lauson Gas Engine Manufacturing Catalog which is all Frost King Engines. It is  32 pages. Face stapled and front and back are card stock. Really nice  pics of the different engines as well as alot of specs and pics of each size.  Sizes from 2 1/2 HP to 20HP covered. It covers the different sizes and parts, and tasks each model can do. really nice pics of the different engines and parts. It measures 8 1/2" by 11". This has been rescaned and cleaned up. there are no bad pages, marks or missing info.  The engines are really pics. please look at all the pics before you decide. a great addition to any collection.
