Eddie Myers is the guy to contact - he was the last that I know of who was in possession of them.
There is one log still on display in the George Hotel/Pub in Cley - this still has lots of Richard Millington vignettes in it - and the log diary in the North Hide at Cley often has some nice entries to.
Nancy's was the Golden Era of British twitching and something very sadly missing from today's scene of instant news dissemination. The excitement of being in there, 40 or so birders half-eating their breakfast, when either a Little Whimbrel, Black-headed Bunting or Little Bittern was found, was absolutely amazing.
The great thing about those days was the pure excitement. I just loved being at Cley every weekend, often wandering up and down the East Bank with Richard Richardson, Richard Millington and others - just birding - and just bumping in to rare birds as we went about enjoying ourselves. There seemed to be so many more rare birds in those days - from Aquatic Warbler, Great Spotted Cuckoo, through a variety of Nearctic waders to rare gulls and terns. Also, the falls of common migrants and scarcities were much more frequent and sizeable then, and the migrations of Linnet and European Turtle Doves was awesome.
The great thing about that scene too was the sharing. There were perhaps 40 regular car loads that made the weekend visits and we would all be based around that Cley square, dashing off elsewhere should the need arise. In the meantime, we would all be tasked with birding the Norfolk coast, eeking out the unusual and generally enjoying ourselves and relaxing. We would all make frequent visits to Nancy's Cafe for breakfast, dinner and tea, those in there at the time answering the almost non-ending number of phone calls from elsewhere around the country. When empty, Nancy and the other girls would take the calls and jot down in the diary the news. The anticipation of entering the premises and hearing of a good bird were always high and countless twitches set out from there.
In the evenings, it was either the White Hart at Blakeney or The George where we all met up and once again, phonelines there were always on the go. The only downside was the overnight accommodation - either the Blakeney Barn or the Vauxhall Chevette.
I'll never forget just after Nancy's closed its doors for good, I was in Cley when news broke of a Common Nighthawk at Woolston Eyes Nature Reserve in Cheshire. Many of us raced straight up there only to find that the bird was an escaped Cockatiel !
