I've reviewed lots of vintage Crescent wrenches (including those on Alloy Artifacts) and haven't been able to match this 8" adjustable wrench to one of those.
One side reads as follows:
8IN. MADE BY CRESCENT TOOL CO. JAMESTOWN, N.Y. U.S.A.
Other side reads as follows:
8IN. CRESCENT DROP FORGED STEEL
There are other wrenches with markings that are close to this -- but can't find a match. If anyone can give me an approximate date on this wrench, it would be greatly appreciated. Thank you.
