Thanks for the reference - will see if I can track it down.
[geek mode] The most authoritative sources I can find on the division in Italy are William Marshall's articles in the SA Colours Series, and his two books on the SA 6th. But his research is ongoing, and he has from time to time revised his descriptions of the SA 6th TO&E. I have corresponded with him, to ask him to help me to try to fit particular photographs into particular timeframes, and it is by no means an easy process... (Example - there are no known unit records of the division ever having had Sherman IIIs - yet there is a photo of 2 knocked out SA Mk IIIs near Perugia... when did they arrive?)
There are plenty of photographs of SA 6th Fireflies in Italy. The timeline is approximately this: The Fireflies weren't used in training (in Egypt) so most likely were issued once the division was already in Italy (i.e. - sometime shortly after April 1944). The Fireflies all appear in SCC 15, unlike the bulk of the division's other tanks at that time which were in the Light Mud/Black Grey pattern - applied while still in Egypt. In November 1944, the division was pulled out of the line for rest and refit at Prato, and the bulk of the Sherman Vs were replaced by the Mk II 76's. The unit's historical documentation suggests the Fireflies were also at this point replaced by Mk II 76's, but that is not supported by all the photographic evidence... (as I said, there is a photo of both being used by the Pretoria Regiment, at a parade in early 1945 to mark the division's farewell to the 24th Guards Brigade - which had served under command of the SA 6th)...
