I made many of these and sold them. I cut a slot in the top and a hole in the bottom then inserted a plastic removable plug and made coin banks out of them. I never kept a one but did keep some extra brass angle that I used plus I kept the jigs I made that I used to assemble them. When my MIL moved off their farm into assisted living a year ago she handed this to me and said it was mine. She didn't have any money in it though LOL.. Just wanted to share this with all of you that can relate to the ole fuel tanks on a stand. FS stands for "Farm Service" here in Illinois. The fork in the picture is just to relate the size.
