In my secret stash I found this 111 today. I don't know it's origin, but it has seen some use. Tank was filled with what I think is petrol, possibly mixed with ethanol. A bit strange. The holder for the key has come off but was still in the box. The stove was however missing pump rod and flame ring. I fitted a spare pump rod from the newer Hiker+. As I was rummaging my stash, I also found a box with a new unused Optimus 45. Unfortunately it had been stripped of some parts, but the flame ring was still there. So I pinched it for the 111. I emptied the tank, and on doing so I realized that it did not have the collar down the tank to prevent overfilling, so it was quite easy to empty. I filled some fresh paraffin and lit the stove. Flame is hard to see with my ancient phone and I-pad cameras, but it is steady and blue. The box color has the slightly greenish color tone which is nice. I also really like the white control key knobs. I don't know if it is original or replaced, typically the 111's seemed to come with the burgundy color knob. Now I just need to find someone who can help me spot weld the holder for the key back into the case. I have not yet tried to date this unit.
