Tomiki sensei did in fact write such a manual, circa 1938. Published by the Kanto-gun Kempeitai (i.e., Japanese Imperial Army Group Manchuria, Military Police), who hired Tomiki to head to Manchuria in the first place (1935? don't have my notes handy.)
I know someone that has an original of the manual you're asking about, and there are other, older materials regarding this particular branch of aikibujutsu, as taught by Tomiki and Ueshiba to the Japanese Imperial military; I've seen them. Some of the materials are from the Kobukan, or, at least credited to the Kobukan, and date from the mid-1930's. The manual you ask about is, in fact, very, very rare, but it exists; I saw a notice for an original for sale in Japan a couple of months ago, from a very reputable dealer, but by the time I contacted the seller it was already gone. :<
I saw a thread on this some time ago. See:
http://www.e-budo.com/forum/showthread.php...ighlight=tomikiThe manual is, as far as anyone seems to know, completely unique. About the only link in writing between prewar aikibujutsu and the postwar derivatives.
And, what's even more interesting perhaps is that it seems there are directly derived arts from this prewar 'aikibujutsu' being practiced today.
What's the question? and, perhaps, who's asking? Some of the aikido world is perhaps not ready for bits of this! I can probably find out the correct, complete title.
