R. M. Auctions has added much more information about the Milhous
Collection Auction to their web site.  There is a list of the musical
items at

http://www.rmauctions.com/milhous-collection.cfm?section=lots&SaleCode=MH12 

At present, it is just basically a list with the note "Check back soon
for complete catalog description" with the items I looked at (stuff
that is not likely to bring more than $5,000 to $10,000, except for the
Milhous connection provenance).
