I'm afraid they're long gone.  I was a did a little work for them
(not on the nickelodeons) about 25 years ago.  They probably closed
up 20 years ago.  Yes, the used the Aeolian players for a while.
Cracker Barrel was one of their early customers.

Some of their early nickelodeons were built with the old upright
players.  I think they all used the "O" roll with the frame bought
from Player Piano Company.  That's about all I know.

Good Luck,
