Apparently there were supposed to be 12 volumes of this series, but I have never encountered the remaining two volumes. There is a listing in the back of one of the older editions in this series which shows the remaining two authors as being Maeda Nobuaki 前田陳爾 and Yamabe Toshiro 山部俊郎. Wonder if they were ever published or if they were just planned but never completed.

These books are now difficult to find and usually expensive to obtain.
