Richard Stibbons asked what was the "official" rewind port for Recordo.
It is the #5 port from the left of the tracker bar.

Motor shutoff varied widely, as there was no "official" port for it.
Commonly it was a port or lever associated with the take-up spool, but
I have seen it tied to the Repeat port on the tracker bar.  This is
#4 from the left.
