I have had this stove for quite a while. I used a similar model during USMC Cold/Wet Weather Training at Pickle Meadows, California in 1982, I don't believe this is the same one. I believe I acquired this one used from a fellow soldier in the late 80's or early 90's. I'd appreciate any insight into the Optimus/99 history (specific and generic), repair/maintenance and parts. I see I am at least missing the wind screen and strap.
