Whether set in the days when Shays and Heislers ruled the forests, or served by contemporary diesels and trucks, the Walthers Cornerstone Mountain Lumber Company sawmill can be the centerpiece of any logging operation. Everything you'll need to start work is included, from the log conveyor to the burner. The mill building is enclosed with board and batten siding and covered with a corrugated metal roof.

This style is typical of permanent operations or those that ran in areas where the weather could turn cold. At the back is a canopied area, where fresh-cut boards are sorted. To keep the machinery running, there's a nicely detailed powerhouse with twin smokestacks.

And for the final touch, you get a sawdust burner, used to dispose of scrap lumber and sawdust from the cutting operations. Typical of buildings constructed from the 1920s to the 1940s and still in use today, the Mountain Lumber Company model fits easily into steam- or diesel-era layouts.
