I’ve had a look at the armoured unit attached to 4th Inf Div and the only one that matches in terms of dates and locations is 42 RTR. Above are some pictures I found of the unit, the top is supposedly on the outskirts of Tobruk 24th Nov 1941 and the bottom one is training in the UK in 1940. So Matildas’ are the way to go for armour.
Also, does anyone know what the vehicle in the background of the bottom photo is? It looks like a mock up to me, the front turret looks like it might have come off a Rolls Royce armoured car.
