What Is It? - March 2015

Rob Battis of Chilliwack, B.C., writes, “I found this in an old tool box belonging to my wife’s grandfather. It might be a part of a larger device, as it has teeth cut into it that could have been used to place it at different heights. At the top, there are two hand-tightening screws to hold something in place at adjustable angles. What could it be?”
