What brand socket is this?

This socket has a marking on it, but no other writing other than 9/16 USA

hello jdr6385 and welcome to the site!

you might find this link handy

this one too

here's a thread showing all kinds of manufacturer's logos and markings. it's kind of a mess.

here's Alloy-Artifacts list of logos and trademarks, but his doesn't include ALL logos and trademarks

your socket was stamped out by Litton Industries (dba "American Forge"), as 3bay notes. they were the successor to the New Britain Machine Company.
