Going through some of the papers I have collected I came across this
notice of a Gavioli catalog that might be of interest to some MMD'ers.
It is a 27-page undated catalog by Gavioli & Company, Paris, titled

  "All kinds of full band organs & slot pianos for shows,
   merry-go-rounds, dance halls, skating rinks, etc."

Copies of the catalog, published in New York, are held by these three
U.S. libraries: University of California at Berkeley, Minneapolis
Public Library, and Cleveland Public Library.
