[GreenKeys] Houston - 28 ASR and 28 ROTR available

[Paul Heller]

Nice Kevin!

My guess is that the machine is either geared for 60WPM or 100WPM and the electronics were a speed converter  / buffer.   It could be that the loop runs through those components and you might need to rewire it to route again to the proper terminals on the terminal strip. Should not be hard to do.

I was able to coax my wife into going along to help by promising to attend a plant sale with her earlier in the day.  Collecting Teletypes often involves trade-offs, I guess.  The gentleman is a mechanical engineer who did not have an interest in the machines himself but recognized them as being marvelous works and thought they were worth saving from the trash bin.  Naturally, I thanked him profusely for saving them.

It is also remarkably clean on the inside.  The keys have quite a bit of the whitish "fungus" on them.  Its background was unknown other than it apparently came from the estate of some high-ranking Naval officer.  The cabinet does seem to have a slightly more "blue" tint than the usual Western Union green.

I can't tell anything about this but my guess is that it was perhaps designed as a built-in electronic TU.  A lot of the wires (practically like hairs) have pulled loose so I doubt this can be restored to its original function and also since there's no documentation on it.  The control panel was very well done.  You can see that it seems to have had some sort of speed selector for both 60wpm and 100wpm.  The switch marked "CW" is a momentary switch so I would guess it was for CW-I.D.  On one board I can see the lettering "7490" which makes me wonder if this was frequency-specific.
