This is a top quality early style Crescent wrench marked "CRESCENT TOOL CO. JAMESTOWN N.Y. 4 IN CRESTOLOY STEEL MADE IN U.S.A.". No rust, some very minor wear on the jaws edges, jaws are straight and parallel on this light duty model adjustable wrench. The jaws are almost 1/4" thick at the widest point. 1/2" capacity between the jaws. Weighs 3 ounces. A favorite light duty wrench among many in the 1940's, yet hard to find!  In better overall condition than most!
