Nice! I was just looking at a similar wrench downstairs today, thinking I should clean it. It's got what I think is a capital "E" in a circle, and some numbers — but like I hinted at, it needs some cleaning. I've moved this wrench out of the way for just about exactly long enough and only now learn it's a buggy wrench. Thanks, Jim.
As I recall E could stand for Emerson. Chuck Garrett
