Hi Jeff. Maybe you didn't see my post in the GS thread. I believe it's Russian.
I'm not going to attempt the name. There are some threads on it. I ran into a 1/2" t handle a while back and was unsure on it. I was pretty sure it wasn't Herbrand but wasn't quite sure what it was. Now I know.

Interestingly, we are seeing more and more Russian made stuff show up - hence my fascination with it. Unfortunately I don't know the language so it's been difficult to ferret out any information.Imagine the back story about how a wrench made it from Siberia to Ohio.
