Ok, I know this is an old old thread... but I’m happy to add an SV pawn shop find.

Serial is SV 7725xx Pinned lanyard plug. Matching numbers including the stocks. Matte blue finish. No letter, but I plan to letter it soon. Oh, and no “S” in the side plate and I looked hard for it.

Amazing info. In this thread... thank you... I understand the passion these safety Victory wheel guns create. Mine is in perfect working order... I plan to get some proper wad cutters and see how accurate I can be... maybe do a bowling pin competition. Smooth as butter double and a superbly crisp and light single action. Feels great in hand... difficult to match and to explain.
Once I figure out how to add pics I’ll add them ... sorry
