Your most interesting forum has been forwarded to me, and I have
looked at my rolls of "The Rite of Spring".  They are listed in
the Aeolian Company catalogue under "Sacre du Printemps", four
large rolls costing 11 shillings each in 1924: T24150, T24151,
T24152, T24153.  The corresponding Universal rolls are S11900,
S11902, S11904, S11906.

The transcription seems to agree with Stravinsky's piano duet
reduction published by Boosey & Hawkes, publication number
B.&H. 17271.  Roll 1 ends two bars before figure 48, Roll 2 is
figure 48 to figure 79, Roll 3 is figure 79 to figure 121, Roll
4 is figure 121 to the end.

A minor correction to the earlier posting [200417 MMD]: the Pleyela
edition is nine rolls, not eight.

I hope this is of some help.  Greetings from a very sunny but
closed-down UK.
