After my first visit back in July, this has sat on the "must go back and have another go" list for too long. So today was the day.
This time, instead of my GPS leading me to the final GZ (which is pretty useless on its own), I was taken to the correct spot to then collect the further clues. So after a quick run around I managed to finally get in and unlock this cache's secrets
Left a Pair of Lederhosen legs TB
TFTC, even though it was rather protracted!
