Wooden bar clamp with wooden screw. Consists of a 30.75" wooden bar with eleven rounded notches; an upper wood piece riveted to a moveable metal bracket that slides up and down the bar and may be seated in one of the notches; and a fixed lower wooden piece mortised and pinned to the bar. A wooden dowel is set above the highest notch, extending 0.5" outward. A wooden screw, 10 7/8" long and 3/4: thick (its handle is 1 1/4" thick), is threaded through the lower wooden piece from below. The screw appears to be oak. Clamp is stained and discolored. Metal bracket shows rust.
