Thank you for your replies,
I first started Aikido with the Aikikai style close to twenty years ago. I now am in Shodokan (Tomiki) Aikido. Right off I noticed a difference that I attributed to the difference in teaching methodology. But now I see a distinct difference between the two styles that I feel is because Tomiki Sensei learned Daito Ryu Aikijujutsu from O'Sensei. I was wondering what influence if any O'Sensei had on Professor Tomiki after his return from Manchuria.
You raise a good question.
From my own research and chats with one of the JAA Shihan, it appears that after Tomiki received 8th Dan from Ueshiba M. in 1940 when Ueshiba first adopted the Kyu/Dan system, Tomiki was effectively recognized as a master of the syllabus taught to him by Ueshiba M. In 1938, Tomiki had already left to teach in Manchukuo (China) and it is recorded that Ueshiba M. visited him there and conducted seminars up until 1942.
Since 1938 Tomiki already had the idea of systematizing what Ueshiba M. taught him in a similar fashion to how Kano J. systematized Judo from some of the Koryu Jujutsu. In fact Tomiki spoke to Kano about this before leaving for Manchukuo. As a professor of Budo at Kenkoku University in China, Tomiki furthered his approach towards structuring the way Aikido/Aikibudo was taught.
Given this scenario, by the time he returned to Japan from his Siberian Internship in 1948, Tomiki was teaching and developing Aikido on his own for approximately 6 years (1938-1944/5) in China. It would be interesting to know the details of the meeting they had in 1949 at Iwama when Tomiki went to pay his respects, but at least from the written stuff I've found, it appears that there was limited contact between the two after Tomiki's return.
One more thing about the Shodokan/Aikikai link - In 1970 Tomiki K. sent Nariyama Sensei (Technical Director of J.A.A.) to study under Hirokazu Kobayashi (then of the Aikikai) as part of his own training. So besides Tomiki Shihan's direct exposure to Ueshiba M. in the "old school" (DRAJJ/Aikibudo) I think that through Nariyama Sensei the Shodokan system is also benefiting from the post-war Aikido of Ueshiba M. as taught by Kobayashi H. who, like Tomiki was also a regular Uke of the Founder.
