Hi Peter,
although there is no indications that a standards switch was ever fitted the T23 timebase chassis has pre-set controls in series with the front control panel frame and line hold controls.
An interlace diode is present on the chassis. It was a diode connected AC/HL triode now replaced with a Mazda V914 double-diode.
Considering the T5 design was finalised late 1935 was a standards switch fitted to the early T5 sets?
The timebase chassis in the T5 set under discussion omits the interlace diode.

DFWB.
