Hello, I found a potbelly stove whilst cleaning out a farms shop. My dad says he vaguely remembers it heating an old wood barn. I had someone look at it and they said it was probably made in the 1950s-70s. It says made in West Germany and I think it burns coal and wood. Here are some pictures of it. Why does the fire grate pictured above have a movable piece on it and what is it called? It looks like the fire got too hot once and broke part of the grate off too. Can I use the stove outside without a pipe on it and is it legal in California? What is the value of it too with a missing bar for the cooking lid and a broken fire grate?
