Lowden, old boy, the fiddle's label is a fairly comman homage to Mr. Stradivari. The custom of putting the label in signified that the actual maker was tipping the cap to the man whose design significantly improved the instrument, not that somebody was trying to put over a spoof. There are hundreds of thousands, if not millions of other violins out in the cosmos that have similar labels.
The instrument probably isn't worth much except to a new student, but you should have a knowledgable person give an informed opinion.
There's no way for us to know what quality your student violin is over the intrawebs. It is likely to be at least more valuable than firewood.
