That's one way to spin a legend, but I’ve never seen that score in a Vatican file—if it’s there, it’ll be locked tighter than a sealed vault. Still, if your sketch has a hidden signature or a weird ink blot that only a 17th‑century scribe could have used, keep it. Anything that could tie a Strad to a misprint deserves a proper look, even if I’m not buying the whole “mystery” angle.
