This is a very nice used magnetic base indicator or scribe holder marked "STARRETT NO. 657" MADE IN U.S.A.. It has a push button on/off switch that works fine but has a few dings and some wear on it. About 90% of the original paint is still intact, the rod and the double ended scribe rod, and the swival clamp are all clean and rust free. There is an indicator adaptor also included. Buy this used one at about 1/2 the cost of a new one!
