I looked at this for a long time when it came out but couldn't identify the man. He looked very much like another famous person so I spent ages on that dead end, before finally concluding that all bewigged men look the same. So I put the puzzle aside.
Then a year or so ago, when wandering around the Internet, I just happened across the man. I did some more research but still couldn't solve it.
Earlier this summer I was thinking about another puzzle and found the man again - I'd forgotten all about him. I was going backwards. I decided to have another go at solving it and this time made sense of another of the clues.
How to get numbers out though? I'd tried quite a few things before but nothing had worked. Then one Friday lunchtime I was having a pint (of London Pride) with a work colleague. He's a non-cacher so I had to explain the various ways that co-ordinates can be encoded. I showed him all the clues, and of course this time I could see it. A great puzzle.
Out today to pick it up. It started raining quite heavily when I left the car but fortunately at the GZ it was a quick find.
Left a keyring and took the little angel.
