In response to Marcus Pregler's posting [020331 MMDigest], I would
offer the following comments as to the Mermod Freres music box:

a) It is a Sublime Harmony Piccolo format;

b) The cylinders are interchangeable with other cylinders of the
same format;

c) Unless the owner has sufficient experience cleaning cylinders
I would recommend letting a professional handle the job; and

d) Although such cylinders do turn up, it is a very rare event.
