I'm afraid Antonella does not know enough about the stage.What I wrote about the use of telephone lines in that office was simply what Danilo told me. A few days ago I had to call Praga, Olga, and he said -he said to me - that starting from that moment it wouldn't have been possible to make any call abroad, neither directly, nor through the centralino-operator. So, Antonella, I think you are wrong. Either you are wrong, or Danilo changed his mind, without communicating such a change to anybody; or to anybody but you.
