I'm not sure if this is the right place to post an auction, so feel free to move it.
Not mine, but I have personally seen this collection. A lot of really nice stuff there. You can eat off of the floor of the metal building he stores these tractors in. He has an electric C185 for sale as well. I don't think any tractor he owns would disappoint. I'm going to be by his place soon, so I can check anything out if anyone is interested in anything in particular. Shoot me a PM if so.
