I don't think O Sensei has the need to teaching newaza, especially at pre-war times, when his students usually had judo (from their school days) or other forms of traditional jujutsu experience, and much less teaching basics like kata gatame/arm triangle choke.
Masatomi Ikeda S. is a 4 dan in judo besides his 7 dan in aikido. If he sees relationship between both arts and wants to show it, no problem. But I don't think he is showing "pre-war aikido".
In the Julio Toribio S. clip what you see is mostly Iwama style aikido.
Anyway, enjoy the pics:
