Hi everyone. I recently bought a Thirty from the neighbors down the road. Their dad had purchased it many years ago they didn't know any history on it. They knew I am interested in old equipment and contacted me about buying it. They made me a deal I couldn't turn down. I did get it running after 40 plus years of sitting in a shed. I am looking for year this was built serial number S7126. I also am looking for a model and year for an autopatrol serial number 7E39 and a D6 serial number 2h7282. Thanks
