I received the photo of my Dad's WW2 RN ship which I found on Ebay being offered by a US seller.
The ship was used in the North African landings and on D-Day but Dad didn't join it until late in 1944.
The ship's landing craft are conspicuous by their absence and the colour scheme would indicate that the vessel was deployed in the Mediterranean at the time the photo was taken.
Dad's assumption is that the photo was used as an aid to identification.
Anyway, we're both happy with my purchase.
