Welcome, and it pays to ask. I think it's all been said. If you look at the CABE site in detail, you will see what the general masses consider valueable/collectible. It's a fun hobby, but much like a rough boat, considered throwing money into the ( hole in) water, one can do the same with an old bike. If you do the work yourself and sell and make money, or ride and enjoy, WIN, win situation. If you don't research a project and anticipate value after money and time invested beyond your own use, that blows if it is of no use to anyone else. I say it looks like yard art. If that's your taste. Frankly, I'd look for nicer yard art. The tank is sweet.
