Regarding Georgadjis, he was in London for health reasons, on his way back he went to Athens to talkd to Avreof. He asked him to supply weapons to Cyprus even though it was against UN Resolutions. At first He said he will think about it and asked to meet him again.
During the second meeting discussions got a bit heated up between them as to the legality of such action and Avreof had the his guards come into the room, and then told him that if he was not out of there in 2 minutes he will be thrown out.
Whilst Georgadjis was there, he met met with Georgios Papadobullos who was then in Greek Secret Serviece for help in arms which he supplied, which of course was leader of Junta during the coup. So here is the first connection to 1974.
