What do you need to know? It's an antique coal stove.
Do you have the grate that goes between the upper door area where there should be a cast iron burn pot and the bottom ash area? (air intake) That is the first piece to wear out, rust away or melt.
You "can" burn wood in any coal stove, just not efficiently. It will burn fast and not heat nearly as well.
The handle is inserted through the door, then the latch is put on so the square portion of handle turns the latch inside. It must be put on the handle in the correct position, so when the handle is in the closed position, the large ear will contact the stove opening to pull it tight. Then put a washer and nut on it. Both handle install and work the same.
You need the window covering which is called isinglass or mica. The two small holes in the upper door get machine screws through them and there should be a metal piece that matches the viewing holes opening. The mica goes on the back side of door, and the inner frame pinches it against door to hold it in place. Low quality Mica is cheap, you don't need expansive clear. It is peeled from a rock, brittle, and was used for high temperature glass. If you don't want to make it ike original, you can cut a piece of sheet metal, such as used in air ducting, and put it on the inside to close off viewing openings. Use the same two small holes for machine screws and nuts.
The reason it needs to be closed is because of what makes a stove work. The pipe you need on it is called connector pipe. That normally connects a stove to a chimney. The chimney is not just to let the smoke out. It makes the stove work. Air can not get into a box to allow a fire to burn without rising out a stack. This rising hot exhaust is lighter than the cooler air outside the stack. The rising gasses create a low pressure area in the stove which allows atmospheric pressure to PUSH air into the stove to feed oxygen to the fire to make it burn. This air is adjusted with the slider at bottom. The fire will burn much too fast and hot if not controlled to within what that intake vent will allow into the stove. So all those holes for viewing must be sealed to prevent air from rushing in, burning so fast it will overheat the stove and you have no control of it.
