Ok, I've done a bit of research on this one and I believe the publisher was 'Jurgenson':
Does this seem reasonable? This is the best I can do without the real scores. Can anyone verify this? Taking a look at the dover scores would be helpful also. I'd bet that the other Tchaikovsky scores are from the same publisher. Horndude77 23:44, 17 October 2006 (EDT)
In reference to the file of the second movement:
File does not work, AcrobatReader can not open it (Ahandrich 10:46, 25 March 2007 (EDT)) Everything works fine for me, except that page 9 doesn't appear (Acrobat 4.0, Firefox 1.5.0.12). —Mathcello 21:54, 14 June 2007 (EDT)
