I couldn't come up with anything definite, but wasn't there a way
somewhere to identify the age of a piano, based on the serial numbers?

My player piano has three different serial numbers on it: the cabinet
is all stamped with one, the sounding board brass has one stamped into
it, and then the player mechanism itself has a third number.  Since my
player seems a little, um, odd (and I mean that in the most pleasant
way!) I'm wondering the history behind it, because I'm thinking that
it's getting to be (if not past) the 100 year mark.

Thanks!
