Info Please re: AEC Matador

[Bob McIntosh]

Here's a photo of my father's truck taken in England in 1940 or so. He served with the 5th Medium RCA, 7th Battery as a BSM.
My question is - would these trucks have been used in Italy ?
I know from records that the ship that carried 5th's original guns and gear to Italy was bombed and sunk by the Germans.
Any info would be greatly appreciated. I also have a few more photo's of his truck if anybody is interested.
Cheers
Bob
