I wonder whether any ARSC member can give me information about one  or two 
aspects of these discs or direct me to a place where I can find that  
information. I hope so.
 
  To begin with, they're well-known. As well as very scarce. Auer made  
them for Victor in preparation for his 75th birthday celebratory dinner in New  
York City in 1920. They were pressed by Victor as one 10" and one 12"  
single-sided discs, with custom black-and-white labels containing a photo of  
Auer and reproduction of his hand-written dedication of them "to my musical  
children," plus the musical titles in Victor's standard typography.
 
  I got copies of them from a Chicago-area violinist and teacher named  
Ruth Ray. Miss Ray died within the past decade, aged at least 100. She'd 
studied  with Auer in Leipzig in 1913 (together with the equally young Heifetz).  
She told me that the records were distributed at Auer's 75th birthday  
dinner. She also said that only Auer's favorites among his pupils received  
copies of both records: everyone else got only one. She got both.
 
  So, my question: does anyone know how the Auer records were  distributed 
to his pupils and colleagues at the 1920 celebration? If, indeed, he  gave 
both to only a limited number of people? Is there a way or place to find  
out? And finally, is there a way to learn how many copies of the two matrices  
Victor pressed? And is it correct, as I've read, that the matrices of the 
Auer  records were subsequently destroyed?
 
  Thanks to everyone.
