I have two....very slight difference from what you state (I think - no "Made" with "USA"):
1) Williams 1128 - markings of the <W> above "USA", "THE "SUPERRENCH"", and "1128" on one side, and "7/16", "CHROME-ALLOY" and "7/16" on the other
2) the very same wrench in the 1/2" version, but where I can't make out the part number stamped.
They are both DOE 90 degree angle wrenches. They are yours no $$ if you want them. I'd only ask for details on their specific purpose.....and you can do that in PM if you'd rather.
