Reel 1 contained the first 14 minutes of the film (introduction by Deems + Toccata and Fugue in D Minor), and Reel 4 had the other 2/3 of the Rite of Spring. Worst case scenario, the mag print that I have for the soundtrack is thankfully complete without a single splice, so for the time being I can substitute the missing IB Tech reels with the same ones from the mag print. In fact, the plan was to have both prints scanned anyway so that any missing footage from the Tech print could be patched using the mag print scan, whether it was the occasional missing frame or, in this case, a whole two reels of Technicolor footage.
