Re: Nos bottle / gas tank please help
Old fire extinguishers can sometimes be had for the asking. Look for a local company that services commercial building fire systems. Old, depleted or out of date extinguishers are usually sold as scrap metal and a company that deals in fire protection will have a lot of them on hand. Ask nice and tell them what you need one for. Good luck.
