Not too much I'm afraid. It was fabricated way back in 1714 by a famous Italian craftsman named Antonio Stradivari. He had made a bunch of Stradivarius violins actually, and each one was individually named over time to identify them.They are regarded as the most outstanding instruments ever made... and no two sound alike they say. Incredible.”— Agatha Egglebrecht
Stradivari is considered to be the best violin builder in history. The name "Stradivarius" (an instrument made by him) still makes an instrument worth a lot more on auctions.
Antonio Stradivari is mentioned-only in Fallout 3.
