RE: Old Coleman Picnic Propane Camp Stove
If it's a "5402" like the one at this link, it takes the old "ball-to-needle"-type propane bottle, see below. They don't make them anymore...I have no idea if/how one might go about adapting the stove to the screw-on fitting now in use/available.

There's a little info re. the original canister at this link.
I still have the Hank Roberts stove! gosh they were great and so lightweight. I carried on when we hiked the Appalachian Trail during the summer. thanks for the memories! soryy to hear they don't make these style cans anymore.
