When I built the beautiful Fine Scale Miniature sawmill kit, I modified it, using the blackmith's section of the building as a company office, which I furnished with a sofa, desk, and hand-painted Preiser figures. If you look at the right rear wall you can catch a glimpse of an intense conversation taking place in the office. I then scratchbuilt a blacksmith's shop with board-by-board construction.
At the left of the picture a logging car is about to unload its timber onto the ramp than allows the logs to roll down toward the mechanism thta feed them to the steam-powered saw. [GPL].
