This is a super nice, very rare mini universal surface gauge, including the original box! The gun blued mini base is only 1.5 x 2.12", and the spindle is 7" long, comes with a very good scriber in 98% like new condition overall. A minor stain on the bottom surface, no wear noted, set flat on the surface plate. The box has some shop dirt on it, but it has a readable label that varifies that this is the original box. The surface gage is marked "THE LUFKIN RULE CO. SAGINAW MICH. MADE IN U.S.A. NO. 521", on the base. I am always looking for these small surface gages, this is the first Lufkin I have seen in over 5 years, and in such great shape too! Don't miss out on this one!
