Both pictures are taken on 17 October 1944 near Venray. Again, not Avalon, but I do think these are A Squadron Westminster Dragoons.
It also shows that the tanks weren't yet fitted with the track link armour, which is something I presume was done about half november.....and a very faint number on the side of the turret, of the crab missing part of the armour around the flail gear-case.
