This is a very nice, antique 10" adjustable pipe wrench, marked "RIDGID HEAVY DUTY 10 RIDGE TOOL CO ELYRIA OH U.S.A. 10" on the handle area, and "B123 ALLOY STEEL " on the adjustable jaw. In good condition with very minimal wear, no rust, good straight metal and gears, missing about 1/2 of the original orange paint. The teeth sharpness is very good. It appears to have been a very carefully used wrench, very few dings, and those are only minor. The knurled thumb wheel knurl works good, good threads.  Measures 9.6" long (completely closed) even though it is marked 10" on the wrench, and the jaws are .7" thick.
