This is a nice clean, precision combination square with the 12" No. 4 Graduation rule or blade that appears to be chrome plated. The blade is marked MADE IN U.S.A.. The square head feature about 90% of the black, original paint intact, a good working level, and a removable scribe. The square head is in very good used condition, and the 12" steel blade is near like new, very good usable condition, no rust or damage. The graduations are the No. 4 Graduation type with 8ths, 16th, 32nds, and 64ths.  Although neither piece is marked Lufkin, we believe it was made in the Lufkin factory with Lufkin hardward and casting form.
