I bought some sockets at a garage sale mostly for a 3/8" SK rachet. There was a bunch of sockets made in the USA by a company called PL MB. There is a symbol between the PL and MB that looks like upside down V. I google it and came up with PLOMB tools. Any one heard of them? They look good. The Rachet turn out to have the retention ball stuck in. Trying to soak it to see if it helps. Well I found this- https://home.comcast.net/~alloy-artifacts/plomb-gallery.html
