[GreenKeys] Two rare model 11 machines turned up in Finland!

Mon Nov 21 01:15:17 EST 2016

The  Model 11 was a Tape Printer which used gummed paper tape that could be 
pasted  onto a _telegram_ (https://en.wikipedia.org/wiki/Telegram)  blank. 
This was the first teleprinter  to successfully operate from an airplane!
see  below and get the photo and blow it up!

Very neat indeed, and a machine I'm +totally+ unfamiliar  with.   

So these machines punched code onto tape that required a trained operator  
to read it? Or did they print in text? The former makes more sense, as then  
the tape could be fed into a reader for re-transmission if needed.

There aren't any DC power supplies visible, so if the loop didn't supply  
power, then they'd certainly need a battery or external DC supply for that.  
But you'd think that 60mA @ 120V would take quite a battery, to not run down 
 in short order.

ABSOLUTELY FANTASTIC!  Congratulations on the  find !
you have achieved what most of us only will be able to dream of!

Juha  the Edison switch is a round   switch with  a  turn knob on top ... 
as I remember it.
Let me find  photo...
do you suppose the motor ran off the  110  or 220 v  and  the battery  was  
for loop  current?

Hey folks:

I recently heard from a fellow in Finland, Juha Lahtinen, who has two  
model 11 machines!  I knew of one M11 in The Netherlands  years ago (the pics on 
my site), but it seems to have fade into  obscurity.

These two M11s may be the only ones in existence.  They have  been 
protected over the years inside crates.

Juha is interested in any M11 information that we may be able to  scrape up.

Hi Gil   

Here is more details from my other TELETYPE. 
Why I think it is Army use.
Color .. then I found small list  accessories in Finnish what  is needed 
for two sets..
1  1 q:ty  Edisson line switch ? ( what kind that that  would be?)
2   1 q:ty Motor Clutch cable  
3   3 q:ty Battery Cable (one spare?)
4   1 q:ty RMP meter with two Probe
5   4 q:ty Battery P-4-60   (This is finnish army code  for Battery) I 
guess two for each station.(one spare)

under the teletype 233 is that serial number?
Speed control I think there is adjustable  resistor  .  during those days 
it was difficult find right stabilize voltage.
you can see 110V .. 220V
in the middle you can see resistor I think it is made for use  220V.

Have a great Weekend

Best Regards  Juha
