The material surfaced beautifully, like what would be expected from a dense hardwood.I asked Knapp what kind of wood this was. "Antique heart pine", his answer. The traditional factory building of 1900 was a multi-storied wood-framed, brick-skinned structure. The lumber used depended on what was available locally that would provide the required strength and dimensions and at a reasonable price. For the East and Midwest at this point in history the answer was "southern yellow pine", with vast forests of old-growth trees found from the Carolinas to Texas.
The "antique" part of the term is obvious. It refers to recycled, re-claimed and river-recovered old-growth wood. My Studebaker wood is plus or minus three hundred years old; one hundred years spent in the building and about 200 years old when cut, determined by counting the growth rings.
