I hope this brief chronology helps answer a couple of the questions raised here.
My wife's father Kenny Breakey was transferred from CC60 to Campo 65, Gravina in Southern Italy on 16/11/1942. (His Diary)
After being taken prisoner at Tobruk, he arrived from Benghazi via Southern Italy and spent part of the winter in Section M, CC 60 near Lucca, according to his official war record, arriving on 31/7/1942.(Diary)
CC60 was clearly set to to house the North African captives having been just set up on 7/7/1942. (telegram)
It was as described in the telegram as a " Tented Camp in two sections with no Heating or lighting.
We have a pencil drawing of the tented camp done by "Brown", possibly Jack (John Thomas), the only visual record we have seen of what this camp looked like in winter 1942 as the inscription to Kenny states. It was done on the back of an Ali Baba page (in Italian) as you are aware, paper was rare and not normally used for drawing.

Kenny kept it with him until he returned home which is quite incredible given what he went through after CC60. (Happy to share this with genuine people who will keep it private).
Kenny did not go to PG 70. (The SADF stated to that they did not keep a record of any information about "His" POW years in Italy and Germany except that he was a POW. Hard to believe but probably true of all the SA troops).
The malaria story from this chat refreshed Lucille's memory as Kenny definitely had malaria, as did many of his friends in the camp who told the same story directly to her after the war. (Up to now, we thought it was an African disease).
Given the inscription on the drawing done by the artist "Brown" which refers to "Grim days in winter" 1942, I would have guess this depicts Campo 60 in November in 1942 just before they left.
Kenny states "this camp condemned and we might go to Rome" so they knew they were going to move as early as August of 1942. (Diary)
Kenny was transported in bitter cold weather in unheated cattle trucks and arrived at Campo 65 Gravina on 18/11/1942 where they had no (heat) food or bunks so they slept on the cement floor. (Diary)
According to the Red Cross records he was still there in March 5 of 1943.
He left for Sagan Germany on16/9/1942 on German cattle trucks and arrived at Stalag VIIIC on 25/11/1943. (Diary)
The Red Cross confirms he was there on 8 November 1944.
According to his war record, he was liberated by Patton in April 1945 after surviving the 6 week "Long March" in the dead of winter.
Let me know if I cane be of any more help.
