[Milsurplus] TG-5 Telegraph question and part needed

[Jack Antonio]

First. Does anyone have a spare BZ-7-N interrupter
out of a TG-5B? It appears that the one in my unit
is utterly dead. Failing a spare, I may have to
build up a little 1kc tone oscillator to take its
place.

Now for the question.

I've been playing with my two TG-5s, and am wondering
about their usage.

What units were assigned these? My thinking is that since
field phone wire had to be run to these units, why not just
issue them an EE-8 field phone? The phone would not require
a trained morse operator.
