That looks just amazing to me. I know the industrial revolution in was in full tilt back then, but it's still amazing realizing that they could design and build such things as well as they did then. Today, we have so many technical tools at our disposal (CAD/CAM technology, etc.) but back then it was pen, paper, willpower and muscle.

Respect!
