SN is 360852. This welder runs and welds perfect. It has a R-57 idler that works as it should. This welder isn't beat up or rusted out. I will get pic's on later today. I dont think you will find a nicer original shorthood. I will take 2500.00 for it. Dont really want to sell it but I need a little more to pay off my 300d. The trailer does not go with the welder. Welder is located in southeast Ohio. My father-in-law can deliver welders or meet somewhere for 1.00 a loaded mile. Contact Dwight at 740-680-2178 or dlbrearley@yahoo.com
