P.S. iCaMp, I used a picture of a captured M11/39 rather than a M13/40 - because I already had one in my Imageshack collection. That is probably why you didn’t notice the gun.
The Australian War Memorial (AWM) has a searchable database of military photos. One of the best photos of a M13/40 in Australian service is this
one.
The AWM in Canberra is a very interesting museum. It has a website
here.
