My bike-boom era published-in-1972 Second Bicycle Two Wheel Travel Camping and Touring book recommends (remember, this is in 1972!) the 111B for group tours of four to six riders. For groups of two to three, they suggest the similar but much smaller and lighter Optimus 8R. For one or two, they recommend the Svea 123 with provisos on its sometimes cantankerous start-up:...
I bought my 111B in 1972 or 73.
I do not recall exactly when I bought my Sveas, but it was soon after that. There was a tiny little store on the edge of downtown Minneapolis that was moving. Their store was on the second floor of a small building, maybe a thousand square feet of showroom space. They had a box of stuff that did not work, I offered them some small pittance for all of their Sveas, there were four, they accepted it. I got them all to work but needed to buy a few parts. Someone else in the store saw that and then offered them even less for all of their 8R stoves, and they took that. I should have made my offer for the Sveas and 8Rs.
I last used one of my Sveas for backpacking in Grand Canyon in 2014. Still works.
