Vintage Coleman Peak 1 Stove Model 400 Lightweight Backpack Stove

Stove has not been tested in a while. They worked when I dried them and put them up last year. I did not want to refuel them, only to have to drain and dry it out again for the delivery. If there is a problem please let me know. These are older units, maybe some dust or debris present, and may take some experience or finesse to get them up to optimal performance.  Been stored in a dry area.  Ships priority mail from Alaska.
