[GreenKeys] Lamp bulb in M15 table...

[Kenneth Gartland]

Hi all!

I'll take an "Educated guess" at this one...

Quite possibly this machine may have seen service
for the hard of hearing society, they placed many
surplus'd M15's in homes of the hearing impaired
or deaf...

I have seen several of these machines equipped with
similar lamp set up, but as there is no room on a standard
M15 table, it was usually external...

They​ 15 indicator lamp was turned "On" by an incoming
call thru the fone modem...

It wud stay on until manually switched off, or the call
"Cleared"...

In the case of this machine, it, the lamp, was placed
inside the stand...

It is quite possible the machine had been originally
installed at or near the head of a set of
stairs, where it cud be easily seen from below...

Just speculation on my part!

Jordan's theory of the lamp being in the M19 table
used as a DC ballast lamp makes sense...

The 19' sets used a variety of power supplies
including the REC13, which cud power a warehouse
full of tty's!

73'
