GPO didn't use the
700 style with inbuilt transistorised ringer as produced by Ericssons - the N diagram shows a Tele 706 converted to local battery used in conjunction with a Bakelite cased Generator 26.
Bakelite phones survived for a long time often where the subscriber would let them go.
I was thinking more of the GPO purchasing new Bakelite telephones like those in the photos of the Tele 164s from the 1960's - one as late as 1966 !
