Hi Dave;
Those markings on her are not Canadian. If I'm not mistaken, they belong to a British Independent Armoured Brigade and the maple leaf below the AoS has something to do with the Brigade supporting 1st Cdn Inf Div from sometime during the Italian Campaign. I'll look it up and let you know. I believe the Brigade was thirty something, maybe 34th, but I'll confirm and get back to you.
Cheers
