[GreenKeys] Teletype Model 3321 ?

[Henning Treumann]

Hi Tomas,

the model nomenclature 3321 is the European Export version of a model 33.
Mostly fitted with electronic control boards made by the German importer
Teleprint.

I can recommend to join www.telexforum.de where are a couple of guys
have been working at those export versions already.
