Not sure whether I have already mentioned this before, but No.20 RHODERICK DHU (bogged on the beach at Westkapelle) appears on a Canadian photo, shot on 6 Aug 44 by Ken Bell near Thaon, Normandy (MIKAN No.3224832, negative PA-160834):
When first seeing the photo shot at Westkapelle, I initially thought that the fading of the turret number outline had been caused by seawater erosion, but it looks like it thankfully occurred much earlier, thereby enabling us to identify No.20 as the tank on the Canadian photo.
