It was found in a toolbox that had several Walden sockets in it of a newer, chrome variety.The toolbox was purchased in the town of Worcester as well so it seemed a reasonable supposition, but I could find nothing to confirm that it was such. So I found a forum full of experts (yeah, that's you guys), registered, introduced myself and asked the question. It just seemed like the right thing to do. Thanks for any information which you might be able to share.
