I was thinking the Yugoslavian region for the vehicles Paul
The vehicles that the SS just gave to whatever units they tried to stand up to fight the Partisans in the Macedonian region.
I agree that a lot of ex-Italian kit would have been used in Yugoslavia, the Croats also got some from the Germans (see AoO vehicle notes). They were also used in Italy, post Italian surrender. At least 1 M13/40 or M14/41 (more likely) was used by the Germans against the '44 Warsaw Rising. I have memories of L3/35 with German troops from photographs (or at least they looked like German troops).
In the "Da Paul Challenge" thread there is a photo of what I am fairly sure are German troops using a handful of AB 41, they must have been fairly regularised as the nearest vehicle has a German star tipped style antenna which was peculiar to some of the German longer ranged higher command link radios. In the same thread there was a photo of an ex-Polish TKS manned by Luftwaffe (air base security most likely) armed with what looked like a MG 15 (an aircraft flexible MG which, though not belt fed, was roughly equivalent to the MG 34).
The ex-French (initially) and ex-Italian (later) stuff along with older German kit like the SdKfz 221 were the commonest issue to
Heer and
Polizei security units. Rear area rail security armoured trains sometimes had a pair of wagons each loaded with either a Somua S-35 or a Pz 38(t) for off rail pursuit of partisans.
