This stove (and the 9F oven-less version) was made in 1934, the last of the early U.S. Coleman camp stoves with a generator mounted parallel to the fuel tank. It was also the first Coleman camp stove to use an Everdur fuel tank, made of a copper-silicon alloy. This feature is touted on the paper sticker inside the lid. It is almost identical to the earlier 2E with the exception of this bronze painted fuel tank. In addition there is also a drain screw on the burner unit in case the stove is flooded. This stove has the same "slant" fuel pickup as the 2E/9E, which results in the fuel valve coming out of the fuel tank at an angle. It also has a pre-heat cup incorporated into the cast iron burner casting, even though it is an instant-lighting model. It has a cast iron "toothed" burner cap. There are three fuel control valves, a main on the fuel tank, another on the generator and the auxiliary on the left side of the second burner, attached to a spring to allow it to be stowed inside the case. The main valve is turned 1/4 turn at start-up, and allows for a fuel/air mix, then when the generator is sufficiently hot and the fuel mix is vaporizing, the valve is opened all the way. The valve on the generator is then used to control fuel flow to the burners. Making the mistake of only turning off this secondary valve will not shut off fuel flow entirely, possibly allowing the stove to flood if the flame goes out. This is possibly the reason for the drain between the burners. The fuel tank/generator unit are separate from the rest of the stove, and can be stowed inside and locked into a slot in the back of the unit (see the 6th photo). This model was followed by the 2G/9G which is the first model to have the now standard arrangement of the generator attached directly to the fuel valve and fuel tank. The oven has a corrugated sheet steel grate and there is a flame spreader that helps to keep your biscuits from getting scorched. A door opens on the right side to allow access to your food. The oven can be set up without the grate and tipped back to form a warming tray or folded and used like wind baffles as on a regular camp stove. As with many stoves of this era, this stove has lost its identification decal, if you are trying to identify a 1930's Coleman stove that has been repainted or is missing its decal, try this Field Guide on the ICCC site: Stove Field Guide - International Coleman Collectors Club
