This is a newer version and has been being made since the mid 70's. A Built in cleaning needle is in this design . These stoves can still be bought new for around 100.00 dollars on the net. Use Coleman fuel in the States,,, and yes you can use unleaded auto gas ,,,, IF,,, you use the lowest octance you can find.. Coleman fuel is about octane 82.. lower in my state is 87 ,but in Montana it's 85. Auto fuel is dirtier,,, may clog your wick in time,, and more caustion should be used and they could over heat/pressure if not careful
