I am trying to sell my fisher stove and advertised it as a Papa Bear. I had someone who was very interested come and tell me it wasn’t a papa but was a mama bear. The measurement across the top is 20”. The measurement front to back including the front shelf to the back leg is 38-1/2”. The vent pipe then sticks out an 1-1/2”. The inside measurement is 30”. I want to be sure I’m advertising it correctly so what stove is it?
