Ray Chandler could probably help you, but, since Yamaha owns Bösendorfer my first call would be to Yamaha tech support.

There are two sets of numbers on a Bösendorfer. I believe the single five or six digit number is a production number. However, the hyphenated number is the one you're looking for. The numbers on the left will cross-reference to the year of manufacture while the numbers on the right represent the number of pianos they have made of that model. Finding the model number has always been the hardest thing for me to find on a Bösendorfer.
