Ann Bancroft is a former polar explorer who happens to live in my area (and no, the actress in the Graduate was Anne Bancroft). She has traveled across the Greenland icecap, and to both poles, on foot/ski/dogsled. She actually skied all the way across Antarctica, passing through the South Pole on the way. She is in the process of reducing her belongings prior to a move. Which has led to my latest acquisition… the two Optimus 111’s that she took to Greenland, and used to cross the Antarctic. They were bought new in 1991/2. They have homemade insulated bases fastened to them, a cut up sleeping pad fastened to a board wrapped in duct tape. She did this to prevent them from sinking into the snowcap when they were used. She couldn’t remember how she fastened them to the stove bases, but they feel really solid, so I’m guessing epoxy? At any rate, they are part of the unique history of these stoves so at present I have no plans to try to remove them. Though I suppose this might make the stoves more prone to overheating when run in warm weather, what do you guys think? She spoke highly of the 111. Had no problems using them in the brutal cold of Antarctica. Makes me wonder if perhaps these two 111’s hold the record for being run at a lower ambient temp than any others of their kind? If not they have to at least be in the running. Given the soot on them I asked if she always primed them with white gas, or if she ever used alcohol. She said they didn’t carry alcohol, so it was always white gas. Before her Greenland trip she was told there would be white gas available at the start of the journey. But the otherwise reliable 111’s started clogging soon after she started using them. Turns out it wasn’t white gas, but was something else (her recollection was that it was some kind of kerosene). With no proper fuel for the 111’s she was supplied with a classic old Primus which got her the rest of the way across Greenland. She was very fond of the Primus, still has it in her living room, and will not be selling it. We agreed that a primus is as sculptural as any “real” art, and belongs where you can see it. They were properly supplied with white gas for her Antarctic crossing, so the 111’s worked fine and were used for the entire crossing. They happen to have re-run the TV documentary “Chasing Shackleton” on TV just a few days before I bought these. It covered the recreated journey that six men took in sailing a replica of the James Caird from Elephant Island to South Georgia. They used a Primus stove on-board the boat just like Shackleton did, you see it a couple of times in the film. Being able to own and use a piece of history like that is one thing that got me into collecting stoves. When I was recounting this film to Ann I used the expression “they were following in Shackleton’s footsteps”, and she agreed. Then I realized I was talking to one of the very few people in history who actually has followed in Shackleton’s footsteps. The only damage I’ve noticed on either stove is a broken hinge on one of them. Both pump leathers are also broken, and stuck in the bottom of the pump tubes. I’m soaking them in penetrating oil, but no luck so far in getting them out of the tubes. At present I’m thinking perhaps I will clean up one of them as best I can, and leave the other one as found. Kind of a ‘before and after the expedition’ display. I don’t know much about 111’s yet. Prior to this I’ve had just one 111b, with the roarer burner. These two both have a silent burner. Am I right in thinking that when sold these were convertible to fuels other than white gas? What would it take to run other fuels in these stoves? I didn’t get any restrictors or different sized jets with the stoves. Are parts available, or at least fabricable? She is also selling the unused backup 111 that was purchased for her trips. I posted that in the Auctions forum. Or you can look it up in the St. Paul Facebook Marketplace.
