No, Hesham, the Boeing 322, 333 and 333A had nothing to do with CP39-645.
Nugo, I have a 3-view and some documents on the 299J, but don't recall if it was in response to a CP or not.
The entries for C-212 and CP39-645 were: Two variations on the Douglas Model 300 (DC-4E); two variations on the Boeing Model 299, the 299H and 299M (the 299H would be accepted and become the B-17C); and at least two versions of the Consolidated Model 32, which would be accepted as the B-24.
I am, as I said, looking for the original Type Specification C-212 which, as the title suggests, the specifications for an aircraft -- range, top speed, etc. - desired by the Air Corps, in this case a four-engine bomber. Although sent to 86 different manufacturers, it was basically a formality in the Emergency Expansion program. The AAC was already committed to the B-17 and Consolidated, when approached to build the B-17, had told the AAC they could do better. Subsequently, Consolidated built a mockup in a month that would eventually become the B-24.
I hope this clarifies things.
