What became of the roughly 190 leaves missing from the Aleppo Codex, including almost the entire Torah?

The codex was in the Great Synagogue of Aleppo when it burned in the riot of December 1947 and reached Israel in 1958 with about two fifths of its leaves gone. The leaves were never observed to burn, and the surviving pages show no fire damage consistent with the loss. Two leaves have since surfaced from private hands, in 1982 and in 2007, which shows that at least some left Aleppo intact. Beyond that there is no established account. Competing suspicions have been aired, about the community in Aleppo, about those who carried the codex out, and about the institution that received it, and none has been tested to a finding. This is an absence rather than a scholarly dispute: no one holds a position that can be read and argued with.
