Ruger Proof Mark Stamp

An interesting addition to my Ruger Tools and Machinery collection, a factory proof mark stamp. It has what I'm assuming is Ruger's numbering on the side as well as the manufacturer's name. Unfortunately, a hole was drilled through the maker's mark. Thoughts on what is the name?

I guess I just need to slow down and think about it every once in a while. It also helps to have a wife that likes to point out the obvious things I miss. I have another one and the makers mark on it is not damaged and is very legible. Question answered......

Troy,
Schwerdtle Inc., Bridgeport, CT. made your proof die. They are a well known and respected manufacturer of tools and dies.

I believe that is a Southport stamp.
