Joe,
I love your sense of imagination, I bet that the Puffer men would have loved a stove in the wheel house, that along with the heat from the boiler room below you would find the whole crew in the wheel house in the winter.
I have never seen a Puffer with a stove in the wheel house nor a chimney up thro' the roof, with your type of build you can let your imagination run riot, a sky light above the crews quarters, the owners would Never allow that.
I look forward to seeing what your imagination comes up with, great build.
George.
