One piece of trivia is that the Australian 6th Cavaly regiment manned M11/39 tanks at Tobruk in January 1941

The Australian 6th Cavalry Regiment apparently was equipped with captured Italian M11/39 tanks as early as January 1941 for the assault on Tobruk. There is a photo of four of them painted with kangaroos on the hull and MG turret, at Tobruk. The caption on the photo indicates that they had been taken at Bardia. Cavalry carriers, presumably from the 6th Cavalry, were also in action during the assault on Tobruk. At one point, the grounded Italian armoured cruiser San Giorgio fired on them. Earlier, they had fired their MG's at the cruiser.
