At the Sherman Minutia website can be found an image of Holy Roller taken in May of 1944. I've added a screenshot for discussion purposes:

Now an opinion on the tracks, they appear to be the rubber chevron type (T48). So given the date, it is quite likely these were the tracks it wore landing at Normandy?
