In 1952 at Hofstra University, the A/V Dept. recorded stereo using two
Pentron r2r side by side, the recording/playback head of the 2nd machine
inverted, so that the tape (which ran through both machines) recorded two 1/2
tracks of stereo. Worked fine!

Two heads, one film, from what I can gather - the BBC mono machines were
adjusted cut a second track onto used film during wartime shortages, so
the medium had space enough for two tracks. I think the narration of the
programme confirms this.
