Here is a used Coleman sportster single burner camp stove model 502 and is dated 8 - 66 (Aug. 1966). There are no dents to the tank. The Coleman label is messed up and there is some paint loss as seen in the photos. The lighting instructions are on the side of the tank. The diameter of the stove is 5 1/2" and the height is 5 1/4". I have lit this stove. It comes with its box and instructions for operating.
