I'm totally unconvinced by your argument the master grinders and the huge skilled force and factories were there in Soligen just waiting for any kind of order do you really believe they would care who's name was on the tang, and Spain is hardly known for their quality engineering skills, when someone tells you he's talked with old German grinders that admit to making and grinding these 14s blanks I think this counts for something, and many early Filarmonicas had no country of origin stamped on the tang I have one myself.
