What tool manufacturer is this?

[KZ1000J]

Bought some sockets today and I'm just not familiar with the brand mark. Can someone identify who the maker? There was some difficulty trying to focus in on the very small mark so please excuse the quality.

Steven Walden?

Thanks,

KZ

I cant make it out, is it SW ?

Yes, SW.....and it's Stevens, with an "s" Walden. Don't know about the Stevens connection; there was a Walden - Worchester at one time.

Yes, Stevens Walden:

Merger with Stevens & Company
[...] In later years Walden shortened its name to simply Stevens Walden Inc. and sold products marked with "SW" in a particular SW-Circle logo.[...]

I have some odds and ends by them, like this 3/4 to 1/2 dr adapter:

Yes: Stevens Walden (formerly known as Walden Worcester)

Some later sockets are just marked "Walden" (even though it was "Stevens Walden" by that time), some are just marked with that stylized "SW" mark in the oval, and some are marked "SWT" (which doesn't seem to make much sense unless it means "Stevens Walden Tool", but I've got a 3/8" x 1/4" adapter in a set marked that way.)
