I have not seen a lot of these and am certainly happy to own one Primus alcohol stove. Definitely not a fast cooker but more of a simmer stove. I picked up the package today from UPS and very lovely indeed. I do not know when this was manufactured as there is not date on it unless someone can check in the Swedish patent office as it has a patent number. Quite ingenious as the filler cap doubles as the flame controller. I noticed also that it keeps a pilot light even with the stove is turned off to heat up the alcohol in the feed tube. I just puffed and it dies out. Another one to fettle during those cold winter days. I noticed that the tank is not made of brass but really has no rust. It will be a bit tricky disassembling it for a fresh coat of paint after a good cleaning.

Low setting High setting Pilot light One thing that upholds the Primus name is the ability to light up and work even if it has been in storage for a very long time.
