Vintage wooden clamp marked No.811 on the back end of each clamp jaw. Jaws measure 12" X 1 3/4" X 1 3/4". The threaded rods measure 14 1/2" over all. There is a flat spot on the threads of one of the rods, see picture. Clamp is tight and functional. There are no cracks or chips in the wood. Needs a cleaning. Great decorators or collectors piece.
