I inherited a 3" CS-1 with the 2-M stamp several years ago. It came with the box and the following information;
serial #: aywoxxx
product code#: 104228
Spec Ord#: 8063
Up above where it says Model No. in the top left corner of the label, it has 893.
The box is in great condition and come with the wax paper and generic S&W safety and instruction manual.
If anyone is still following this thread and could tell me if this was a service-used/issued revolver, it'd be greatly appreciated.
It also has the medallion RB grips.
