I have a very old lightweight backpacking stove that I am trying to find fuel for. My guess is it is from around 1977 or so. On the base it says "Medalist" and I believe that is either the brand name or the model. On the other side of that it says "Sierra Stove - US Patent 3,648,680" Below that are instructions for lighting, etc. If I remember right - from about 25 years ago - it uses a fuel canister that has a rubber bud on it that the male end of the controller goes into. Neither REI nor Sports Authority have any such canister. It's a 4-piece unit (top, base, controller, flame exit thing) and is only about 5 inches in diameter. If anyone can help me find where I can buy fuel for this stove, I would appreciate it. Otherwise, I guess it becomes an historical backpacking artifact!! Thanks.
