Our Grand Neighbor died a few weeks ago (wonderful, wonderful person, as was her husband, couldn't ask for finer neighbors), and their family has been doing some house cleaning. We went and raided the dumpster and found this curious thing. It's about 6' long overall, the straight part is about 4', 6" wide and 1.5" thick. The large hole is 1.125", and the large nail circle is 3.75". There's a small hole near the one end, a small split, and a dowel put thru and wedged. Any idea?
You can see the tip of the dowel in this photo.
I also recovered an H&R (Harrington & Richardson) saw sharpening gizmo, complete with instructions. First person to say, "I want it!" gets it.
