How rare is a DWM Circle S rework? The Circle S is on the left side of the receiver near the chamber. Can someone provide the history of these? How do you know one is real?

 

[Dwight Gruber]

There are collectors who assert that this is one sign of a Simson rework. There is no documentation to verify this or any other interpretation, and its meaning is ultimately obscure.
