dartymoor: Checked whilst replacing a missing cache nearby and it was quite visible. Decision to archive taken because the puzzle box has indeed suffered some damage (although it's done quite well, overall!) and isn't repairable as the bit of wood is missing. I no longer have any more puzzle boxes to replace it with so it's time to go.
Was fun though and very pleased it reached 23 Favourites out of 83 finds. Thanks to all who tried it!
