Yep, but they were hard wired, not on plugs. Single line Princess phones took 4
conductor solid cable, two line Princess phones took six conductor solid cable.
(I mis-spent the summer of 1964 installing phones for NY Bell and many of those
were the Princess model.)
In 1962 there were only 4 prong square plugs for phones and the Princess wasn't
compatible due to the necessity of an isolated transformer. The RJ standard
wasn't developed and marjeted until the 70's.
Regards,
James
