The vast majority of Panther that served in Normandy were Ausf A, some Panzer divisions only fielded the Ausf A. The Ausf G was a new tank so was there are slim pickings during this period.
Italy again from what I can remember was only Ausf A I would have to check to see if they received any Ausf G.
5th SS Wiking again only ever fielded Ausf D and Ausf A they never operated any Ausf G.
After checking Italienfeldzug Vol 2. 1./Pz.Regt.4 were the only Panther Abteilung in Italy LAH pulled their Panther Abteilung out before fighting commenced.
1./Pz.Regt.4 was mainly equipped with Ausf A but after heavy losses thy received in 3 batches of replacement's totalling 68 Panther between June and November 1944 this was a mixed batch of Panther Ausf A and G the latest batch of Ausf G they received was from late September to early October.
