This is a top quality early style Crescent wrench marked "MFG. BY CRESCENT TOOL CO. JAMESTOWN N.Y. 10 IN DROP FORGED STEEL MADE IN U.S.A.". No rust, some very minor darkening on the bare metal surface, very little wear, jaws are straight and parallel on this heavy duty model adjustable wrench. We note a few owner's stamped letters on each side, "R T".  The jaws are almost 5/8" thick at the widest point. 1.1" capacity between the jaws. Weighs 1.3 pounds. A favorite heavy duty wrench among many!
