There are still a bunch of these still in service, complete with switch
registers and blinkey lights! I do not know who runs them, however.

The newer models dumped the lights and switch register, much like PDP-11s.

Actually, 23" is quite common for telco equipment. Western Electric had a
bunch of standards, all dating from the 1920's, thank goodness that only
two survived.
