Take some pictures of it and send them to Fred Oster at
www.Vintage-instruments.com. He is located in Philadelphia,Pa.... From what I recall he was an appraiser for Christies years ago and from time to time you'll Catch him on the Antique roadshow... I have sold Fred many instruments over the years.
Most likely you just have a decent student instrument, but the proper pics and such will give Fred the info needed to tell you what you've got.
Good luck !
