I have a quality 47 page reprint of the John Lauson Frost King Engine 1916 catalog. a nice reprint of the Lauson engines from 1 1/2hp to 50hp. Many pictures and specs about each of the many engines they produced. Catalog meadures 5 1/2" by 8 1/2" Everthing a person needs and wants to know about the frost king engine made in Wisconsin. has a ton of info on sizes, specs and alot of quality pictures of all the engines. Shows the buzz rig, portable and many other configurations.
