A BUTTERFLY KERO BURNER!!! wonderful--that was my first "primus style" stove..i thought i was the only person who had one--you saved the box too--great--they are not made as well the real things but run fine after a few adjustments--Handi Albert gave me my first bit of advice when i came to the site by telling me to wrap a but of lamp mantle string around the jet to seal the thread--wonderful photos of a great collection---make sure you send some to Ross to get them posted so you can become a "real" collector--as apposed too us "enthusiasts"---
