I'm sure I remember reading, in Ospreys " battle of the rhineland" that the 44th royal tank regiment had a squadron of Crocodiles in Reichwald but this could be wrong as the information in this book is not always correct and the details are vague.
but i'm pretty sure the 1st Fife & Forfar Yeomanry (79 ArDiv) where there with crocs.
hope this helps a bit, maybe someone else might have a bit more info on this.
