Minneapolis Moline M 602 Gas Tank. Its as nice as a used one gets no rust inside and no bad dents. The threads are good also. I could not get a photo of the inside because off the long neck my camera was just not having any of it. Its as clean as a whistle. Check the photos for condition. Please feel free to write or call with any questions. Please look at all the photos and please CALL if you need more info.
