We have Myson LST radiators in part of the house and two of them have the
same problem. The plastic housing for the remote bellows that operate the
TRV have broken on both.

Any ideas where I can get a replacement. Myson have not bothered replying to
emails I have sent them asking if they have a parts stockist, and Google
throws up so much crap that its like looking for a needle in a haystack
among the search results.
