A few. I have a couple of old stoves, and three lanterns...all Coleman. A single burner chrome tank stove that my father bought new in 1947 or '48. A double burner our family used when I was a wee tot...early 1960's vintage. Both work well still. A single mantle lantern, a double mantle lantern...both burn gas; and my favorite is a single mantle kerosene model, the only one I acquired somewhat recently, made in the 1950's...it is a bit rare. All in good working order.
I also have three Aladdin mantle lamps, kerosene fueled.
