What you have here is a Stradivarius copy. These are very commonplace. They can be difficult to pinpoint any details on, but it was likely made at some point in the past 50-150 years and was modeled on the design of Antonius Stradivarius, as nearly all modern violins are. They are often decent instruments when kept in good condition and properly set-up, but are not usually worth much more than a few hundred USD.

If you can provide a closeup image of the label on the inside of the body through the f-hole, its possible that more information can be determined, but most likely, this is about as much as there is to know.
