I have over 200 Ampico rolls and about 6 Welte-Mignon rolls for sale.
I can send pictures of the Ampico box ends to show titles.

I also have the book "Welte-Mignon: Its Music and Musicians" by C.
Smith and D. Howe (1994).  It is in excellent condition, probably never
opened, hard cover, no dust jacket, 975 pages.  Just $200, includes
media mail postage!  Can be mailed in time to put under your Christmas
tree (priority mail $8.00 extra).
