The background image that Mr. Gordon refered to on aiki-jutsu.com can be found here:

It took me a few minutes to figure out if this menjo was correct or not - it does claim to be issued from the "Daito ryu Aikibudo SoHonbu", and is signed and stamped by "Soke Takeda Tokimune". However, as I suspected, this is simply a faded image of the Soke Dairi certificate issued to Kondo Katsuyuki s. by Tokimune s. - most likely lifted from his web page! This image can also be found (and confirmed) on page 171 of CWDRM.
Nice.
They don't seem to mention Daito ryu on their site, aside from a brief definition.
Anyway, this topic has been discussed at length in the following threads (that's why my opening message suggests doing a search first!):
"Senso ryu" aikijutsu/ Hanulak
Torishimaru aikijutsu/ Richard Behrens
I didn't bother to watch the MPEG's.
