I am looking at a beautiful old wooden 'marimba v xylophone'; it has no chimes underneath it and is a 'single deck' instrument (I have seen images with two rows of bars). As you may guess, my knowledge of these instruments is close to zilch.

How might I find the value of this instrument? It has the "Liberty Chimes" metal plate on it, and is believed to be quite old.

Any help is greatly appreciated!
