Very good thread! Two things have surfaced, based on the beast research available (Pranin, Skoss and a few others) :
a) Nobody knows where the jo came from. Some legends say it was a shortening of the Bo, atributed to Gonnosuke; and
b) Ueshiba's Jo as told by Chuck Gordon and Chris Li, among others, probably came from the period of his military service and his training in Jukendo(originally based, as already told, on SMJ and western bayonet fighting). There might be other influences but mostly it was jukendo.
