This is a good useable 6" flex rule marked "NO. C-2105R LUFKIN MADE IN U.S.A. TEMPERED". It has inch graduations on both sides, 10ths and 100ths on one side, and 32nds and 64ths on the other side. It is in good straight condition with good graduation lines on both sides, there is one corner slightly rounded off, otherwise in very good used condition.
