There are about 18 "Patent Repositorys" around the country, that keep the same records as the U.S. Patent office. In the midwest the University of Wisconsin has them,at Madison WI, and the Minneapolis Public Library Has them. I'm about 150 miles from eather, so I use Minneapolis, because i'd get lost in Madison, and the air is too full of "weed" fumes.

The year was about 1967 and my father found a good used Ford 601 tractor to use on the farm instead of "Bob", our old mule.
