Deadly Fighters (1979)

After a few Hours (lol) scouring the web, and the usual suspects for OOP cinema, I cannot find a copy (or stream) of this film -- if anyone has seen it, can you describe it? or any fun details of how where when it came to be?
Obviously, if it is available to watch somewhere, I would Greatly appreciate that
