I like that one. The jaw design and USA made make it an especially nice one. You may be right that yours is not so old, I think the design has been around for a long time though, so maybe it is. I guess it depends on what we consider "old". Usually, when I see them, the COO is left off or is often China or something similar. I know Craftsman had them for a time and may still have. They were called "ClenchWrench".
Here's an Award version, made in Japan. It's hard to see, but the lettering near the hang hole on the one side is "SANKI". I don't know the significance of that, but it's there. I thought I had a ClenchWrench, but if I do, I can't locate it right now. I'm sure someone else does and may be able to pop up a photo.
