Here are the box labels and the revolvers in their stock configurations.
This is the first edition of the Classic Hunter. It is a 657-2 and has the S.N. prefix HTR
The Product Profile ad slick calls this RSR exclusive the Model 657 .41 Magnum Hunter.
There is no "Light" or "Lite" in the model name.
I would very much like to find a Classic Hunter II product code 103948.
