I have located two of the selections you are looking for in my collection
and will scan them and send you the MIDI files:

  66683 The Mikado Selection
  66093 Valsette

My friend Phil Strauss has the other three selections in his collection
and will loan them to me for scanning:

  66801 Bric-A-Brac
  68073 Circus Princess Selections
  67233 Victor Herbert Favorites

Phil lives about 50 miles away from me so scanning of those will have
to wait until we see each other.
