Don't worry next time I'm in Osaka at the Asahi Dojo, I'll smuggle out a copy of the film of Takeda from the late 1930's showing him and all his aiki glory...!!! :0)
Thank you Mr. Western, I didn't want to say it myself. It is kind of one of those things, because some treat it as rumor and debate its existence. If you do smuggle it out, let's hope it is him using aiki and not jujutsu.
