3) The Japanese T-2 came along later in the early months of 1964. It was testing Ed's theories on a shorter tail moment, (2"shorter), and more dihedral.
Maybe, but wasn't important for me. I considered what the unfinished fuselage could be built for. I don't doubt the dates, and maybe the Japan T2 was for testing the winter 1963/1964 theories, as mentioned in the Grid Leaks Monitor. The pusher was a project in this winter. But anyhow, the unfinished fuse is made for the pusher wing and has neither the very long tail of your T2 nor the very short Japan tail. In fact, it reconstitutes the proven moment arms of the contest T1 (as well as the dihedral), just for swept wing. So both carrier T2 and Japan T2 were errors in Ed's trial and error sequence.
