The message
from "Alan Holmes" contains these words:

If you are within 10 miles of Windsor, I'll gladly come and pick them
up, this year the damned squirrels have decimated my tree, where I
usually get about 6 of those plastic trays used by fruit and veg
sellers filled with striped walnuts, this year I have barely one
tray all with the covering still on, and that is in spite of my
attempts to trap the bloody things.

You're not using a proper walnut trap, then.
