My feeling is that those later titles only really existed in Nanjo's fevered imagination. Or perhaps even he baulked at the number of people he was bootlegging...
Some of the material was possibly released either prior or later on other labels - the Baroque Bordello stuff was surely part of that 10cdr set of Kawabata's, and I wouldn't be surprised if some of the Toho Sara and Musica Transonic stuff at least partly corresponds to the later releases on PSF and Fractal. 163 to 165 were tapes on Kawabata's Tenkyo no To label.
I would have loved to hear the Daiyon Kobo Tapes comp though...
