1940's stove heater need information

I bought this great stove/heater because of the cosmetic look and would like to get it working but I cannot find any information. I know it is from the 1940's and the top is etched 100 ECONOMY. I believe the stove is porcelain front and top and the sides are tin? There is a pretty picture of a ship and a boat with people in it. There is not one chip or scratch in the porcelain. If anyone can give me any information on who made it and where I can get it running safely, I would appreciate it. When you open the door, there seems to be everything intact, but I would rather someone else who knows what they are doing to get this working for me....thanks for looking.
