Re: any ideas?
Whatever the quality of the instrument (and the tone of some of the comments here) consider it a thoughtful gift from your Uncle.
Most important is that it is playable for whatever the cost or type of materials. A local repair shop can probably attend to that for not an excessively high cost. I hope you learn to play on it and love the mandolin enough to continue to explore the many different kinds of mandolins, old and new, expensive and inexpensive.
