Help with this wader, please!

I photographed this wader at Cley a couple of weeks ago: at the time I didn't look closely at the images, because I'd assumed it was a young Dunlin. Looking at the photos now, it sees very 'chevronny' with a somewhat longer (Curlew Sand) bill.

I imagine it is a Dunlin, but am I missing something? (No bogus professional footballers, characters from 'Friends' or 'Peep Show' please!)
