Hi Robbie, Kim Bunker here from Orange Coast Piano.  We found out
generally what kind of rolls we have, from Rick and Betty, Larry,
Bob, and Rudy.  Thank you all for your help.

Well here we go: Eugene DeRoy of Symphonia Music Roll Factory,
Antwerp, Belgium.

In the 1920's DeRoy recut dozens of different types of music rolls
for mechanical musical instruments, for famous European names such as
Hupfeld, Loesch, Popper, Philipps, Weber and others.

The rolls we have are from that cutting era.  There are 12 of them.
They measure at 13-7/16 inch [34 cm] wide inside the wood spool
flanges.  Due to enormous curiosity regarding these we have decided to
list them on eBay to the highest bidder.  We also have pictures of them
as well.  The reason is so everyone may see them: eBay No.#194698351
We will ship domestic and international.
