We recently purchased a Carl Frei miniature organ.  I understand these
were made in the 1970's.  This one plays 21 note rolls and has about
35 pipes.

I'm told these are the same rolls that are used on some newer small
organs, but I don't know which one(s).  Since this only came with one
roll I would like to get some more to sell with the organ.  Can anyone
help with a source?
