If authentic, it would sell in the millions of dollars. However, it is unlikely to be an authentic Stradivarius. The Stradivarius model has become the most standard violin model to copy, and many German factory makers of the late 19th to mid 20th century especially put the name Stradivarius with a year on their instruments. If it would be one of these instruments, it could still be worth between $1000 and $3000 dollars.

Depends on your market. In the US, an authentic, pre-89 HK91 (an authentic Heckler & Koch rifle, not talking about the "frankenguns" from Century Arms or PTR)... the last one of those I saw went for $3,000, and that was almost ten years ago. Looking on Gun Broker, the people who are selling the authentic models seem to set their prices between $5000 - $7000.
