Help with identifying unusual brand mark on vintage 1/2 dr. socket

[DadsTools]

I found this socket in a box of mixed drive tools. The toolbox is a Craftsman with crown logo badge, and the other tools in the box also suggests a 1960s to 1970s dating. I've never seen this WW mark before. Anyone know what company this is?

Thanks!

There were a few other sockets marked WALDEN in this box of an earlier style, so that makes sense too. There were also some of those STW marked sockets, also without COO, that I understand are also attributed to Walden. A few of the STW-type sockets didn't have any initials at all, only size marks, but they were clearly of the same make.

Wonder if the WW is a reference to Walden-Worcester, or just an artsy way of expressing the W.

It seems that the company was somewhat inconsistent in the markings on its tools.

Thanks again!
