A new addition to my collection, no markings on the cast body of the wrench, the adjustable jaw has RIDGID 14 forged on it, the square drive is 3/4". I have part of a 1975 Ridgid cataloge that states- Wrench,Vertical Pipe - Page 6, however i do not have page 6. To me it appears to be an earlier casting than the 1970's, and is it a Ridgid product or has the Ridgid marked adjustable jaw been fitted to a casting by some other manufacturer. I have seen later versions with 1/2" square drive made by Ridgid, but never come across this shaped item. Has anyone any information at all about this wrench. Cheers
