This is a nice quality made adjustable depth gauge with the 30, 45, and 60 degrees angle markings on one side. The rule is 6" long with 64ths inch graduations on one side and 32nd on the other. The gage head has the gun blueing type finish, and is marked "THE LUFKIN RULE CO. SAGINAW MICH. MADE IN U.S.A. NO. 511" on it. The gage head is in very good condition, and the rule is in good+ condition with some minor tiny stained spot, and slight wear on the lines and numbers. No owner's names noted. Comes with the original box, also in good shape.
