**** I've added a "bad" video of it doing it's thing.   Sorry, it's sideways but you'll get the idea.   Note:  Sometimes the marble get's stuck inside.  Maybe it's too dusty or it needs a heavier marble--- like a metal one.

I really don't know what this would be called or where it was made.   I found just One similar item doing a Google picture search and it was from a company in Germany and the website was all in German.  So I don't know if it's a semi-unique item made by an Artisan or maybe there is a genre of them.   If anybody has an information, I would be grateful.

It has Xylophone-like striker-plates that have key-tone letters on them and you can change the position of the pieces throughout the tower to change the tune when you drop a marble through it.   It measures about 27 inches tall and the bottom bowl is about 9 inches wide.  The top bowl is about 6 inches.   There are no maker's marks or writing on it, other than the graphics and the tone-letters on the "keys."

It's all in Excellent condition, with some minimal nicks and wear marks.   
What you see is what you'll get---  please examine the photos.  (I'll include one marble.)

US Shipping will be $18.50.... packed well.  International by ebay program.
