I have 2 steel 72's that certainly qualify as vintage. One is a Healthways and one is a US Divers. One had its first hydro in '49 and the other in '58. They both have post valves and the tanks look very similar. On the outside they are in reasonable condition but I have not pulled the valves or the boots. Is there any interest in these? I'd take the shipping and enough to package them for shipping because I hate to destroy them. Or should I fill them one last time and enter them in the "I Like Guns" forum? Offers? Advice?
