Hi Doug,  In answer to your inquiry for Music Box Repair Tools [111008
MMDigest], might I suggest you contact the following hardware shop in
the heart of Sainte-Croix, Switzerland (the home of many of the world's
most makers of music boxes).  They are located just a block or so down
the street from the Reuge SA factory, and they have been supplying the
music box industry, and its finest craftsmen, with tools for over 115
years, since 1896.

I'm sure this 4th generation family-owned and operated shop would be
most pleased to assist you.

Be sure to ask about their handheld gyroscopic screwdriver(s) with
interchangeable tips!  Like an enlarged jewelers screwdriver with
arms, it is a most wondrous tool for installing and removing music
box machine screws.  Every music box repair person should have several
of them, with different width tips, on their work bench at all times.
(Phillips head tips are also available).  In addition to being
beautifully made and exceptionally well balanced, the gyroscopic arms
allow one to easily exert more torque for insertion or removal of comb
screws and other machine screws.  To the best of my knowledge, they are
the only source for this great tool.

Best of luck and good hunting for the tools you will need!

Most sincerely,
