thought I'd never see this again: While it isn't from the far east, it is about another unrecognized or forgotten style of martial arts--namely near eastern ones:
entreri.egloos.com/5075869it's a manual for middle eastern knights (or fursan)--specifically the mamlukes (being from the 15th016th century): foot combat, horse combat, even wrestling on horseback, are all included in this partial scan of the manual.

"Section of fighting/countering on horseback with the hands"
"if he meets you and stretches his hand to your chest to pull you from on top of the horse, then counter his grapple with your left hand, and place your lower arm on his direction, and do not cross with your elbow to the outside of his lower arm, then he is (at this point, I can't make much sense of what he's saying"
