I don't know about the frames, but I know that the rear toggles are harder than a w****'s heart, especially the Mauser ones. I cut a dovetail in a DWM rear toggle with a carbide cutter without any problem. A couple of days ago I ruined a HSS and two carbide cutters trying to cut one in a 1937 S/42 rear toggle. It appeared that the DWM toggle had a hard "skin" and was softer inside, the S/42 was HARD all the way through.
