Have you tried www.uea.ac.uk/~b026515/schemes.html David?
Not seen that one, will check it out. They don't seem to be listed at http://www.cr-birding.org/ which is usually pretty complete.
The form on the uea site for submitting records seems broken so I have emailed one of the people directly. Will update this iSpot entry if I get more details about the bird.
The scheme was the one. They've provided the details and I have updated the entry accordingly.
Have you tried sending the details of the bird to the BTO? It can take a while but in my experience they usually manage to track down the scheme. I would think it unlikely that anyone is colour ringing godwits without having registered their scheme so hopefully you get there in the end.
The ring combination on your bird seems to fit 'scheme 5' of Project Jadrakan on Icelandic Bck-T Godwit referred to on the UAE web-site Ray refers to above.
