This is a unique used combination protractor, level, center finder, and center punch with a cast iron precision machined magnetic base. It comes with a very heavy steel hinged and latched fitted case. The base is 5" long, and the dial face is 2.23" diameter. The protractor will calculate the angle the base is on automatically, via the mercury balanced needle. The dial face is marked "MIRACLE POINT TRADE MARK MERCURY BALANCED", and the inside box label reads "ERICK MIRACLE POINT MODEL 900 CULLEN MANUFACTURING CO. INC. STURTEVANT WISCONSIN". The V knotch is also machined, and offers the flexiable use on round surfaces like steel stock and pipe. The finish is a gray textured paint over 95% intact, The dial face is clean with no scratches or cracks. This gauge works great! The punch is sharp and ready to use. New ones can be ordered if need be. The case is very nicely made, heavy duty, and in very good condition. Inside the case is a Angle-Pitch Chart for pitch calculations, also marked Miracle Point. A nice used tool, at about 1/2 the cost of a new one!
