The Mechanical Music Press web site includes links to a wide variety
of audio recordings of mechanical and automatic musical instruments
from several sources.  Go to http://www.mechanicalmusicpress.com/ 
On the opening page, scroll down to the "FAQs/Resources" heading in
the left column, and click on "Audio Recordings."

Among the many fine sources of recordings listed there, you'll find the
Marion Roehl Recordings and Hathaworld series of collectors' recordings
within the "Paul Eakins Nickelodeon Music" site.

If we've overlooked another source, we'll be happy to add links to
other suppliers of good quality CDs of automatic instruments.
