Hello All!  I found this site through a friend, and it is great!
I am a piano hobbyist (a nut, really) and I have a couple of things
to contribute.

For almost the past 30 years, I have written down every piano I have
seen, and when possible, their serial numbers.  I saw that someone
was specifically looking for Seeburg serial numbers, but I didn't
catch their e-mail address.

Also, if anyone has information on the Weiser & Sons Piano Co. of
Chicago -- serial numbers, case styles, what kind of wood, etc. --
I would appreciate it.  This was a very small concern, only in business
from 1912-1925, and all pianos have 4-digit numbers.

Thanks, Aaron Carlson
