Walden Worcester was a common name in tools before WWII. I have a set of these I've accumulated. Speeder handles, Tee handles, breaker bars, Tee with flex head. Not the greatest metalurgy, as most of what I have shows signs of being bent, and many are cracked. An interesting piece of the time before interchangeable sockets. Some were plain steel, but many seem to have been nickel plated.
