Ok, here goes. I got this stove in Dec. It is a Preway 403. Looks like it was made late 1930s. 3 burner, cast iron manifold and grates, tank holds about 1/2 gallon of fuel. Plug on one end, pump on the other. All I did to make it work was oil the pump leather and fuel her up. The generator is on the left burner.

Fuel can for size. Seems more appropriate than a pop can ( this is Idaho, they are pop cans. Not soda or coke can )

Riot gets in the picture.

3 burning
It burns very well and will add good ballast. Specially with a full tank of fuel. The Aux burners are opened with levers and I believe they do not close very tight as there is good smell of fuel while running in the house. Not enough to go "boom" but it s there and would probably be real bad in a small trailer. Outside no problems. Heat output of the main burner alone is about the same as a 425. It is a good stove. I like it.
On the right side of the tank is some solder. Does not seem to be a hole repair. Holds pressure just fine and from the shape of it it might be for a badge/tag or something. I am not worrying about it.
