I've posted about this elsewhere, but Mike Butcher told me personally via email that they never completed the quad mix of Sabotage. He said they started on one track and there was some kind of technical fault and they abandoned it and never went back to it. He said that the band's attention was so consumed with the ongoing lawsuit with their former manager at the time that everything aside from the stereo mix fell by the wayside.
The photo in the screenshot above is of the Paranoid quad master (WS4-1887) and no Sabotage, sadly.
