Yikes! I don't even want to think what it would take to fabricate that rotor..... Stoegers used to import the MS and had parts lists in the old Shooters Bibles. Wonder if there is anyone left who knows what happened to those parts when they dropped them (if they ever actually stocked them).

You need an MS expert, which I simply am not. Hope one comes along (any help from the German Gun Collectors Assn? Yeah, I know MSs aren't "German German," but they might know of a parts cache....).
