Wading Bird, long beak, Isles of Scilly

We saw just one of these on a beach amongst many plovers, turnstones and sanderlings. It was the same size and profile as a Greenshank, but the legs were not green and neck/breast was beige not white. Consulting books, I wonder if it was a Godwit? Any suggestions appreciated, I would love to know what it was!  Thank you.
