Chippyzip/Graham, if you haven't already replaced the deflector, try Easyparts. They are in Holland, the website has an english language version, and they are very reliable. They are quoting 81€ plus postage for the part. I lost one of mine for the very reason that Mike H quoted - dropped on it's side. Had the new part within a week (I am in France).
Give them a try, I have used them for a number of years and find they are good for all sorts of spares. They also always answer questions about parts etc.
