i found part of a container were i thought this one should have been, we had a very long look, and have all the rest apart from No 3 so i think that may be missing too
We were up last week looking for these and found 2, 3 & 7. It was pretty evident that all the others had gone missing / been stolen and the owner confirmed this. Shame!
i found box 2 on tuesday and there is a list of missing ones inside the book.
which is quite handy for those of you with a clue book but i don't have one as im trying to restart my 100 the proper way.
