This is a nice rarely seen double marking gauge with free spinning marking wheel. There should be two 5/16" adjustable scribe wheel holder, but in this case only one. It is marked inside a diamond shaped logo, SHIPLEIGH HARDWARE C0. DIAMOND EDGE SAINT LOUIS" and in the center of the inner diamond is the letters "DE" (Diamond Edge). The one remaining hex holder has a little pitting on it, but it tightens up and holds position very well. The main head is in nice shape, no rust or damage, very light pitting in a few small areas. A quality made tool!
