Picked this up recently off fleabay - has its original lipstick tube, note the number one, stamped on the bottom rim of the tank. A lot of Primus stoves have numbers characters stamped somewhere on the rim - most are poorly pressed, it can't be made out what they are. This has been a real PIA to fettle. Lipstick needed peening, no overly happy with the flame shot, but it does the job.
The outside of the tin was quite grubby, WD40 applied to an old cotton teeshirt, lifts a lot of the dirt out.
