I acquired my first engine at the age of 11. I have been collecting antique farm machinery since. When I was 17 I began to buy and resell. Examples of what I have include: tractors, gas engines, agricultural related collectibles. See links for items for sale. Also click on older posts at the bottom of this page for more pictures.

This is an engine I bought this summer. It was built in the late 1940's. It was patterned after a model N Briggs and Stratton. There were some patent issues so they were not produced very long. I found this ad in a old farm magazine.
