Bob and I have collected infor- mation on these unusual truss rod flats for years. Mitch Valder, an N-scale modeler who mod- els the north coast of California, joined our efforts. We have many photos taken over the years. Some of our best photos are cour- tesy of Mike Kellogg of the Timber Heritage Association in Samoa, California. Another THA member, Thad Wuest, photographed and measured a mill flat the Associa-
