Putative Kumliens Gull in Denmark?

Hi all
Some of you might have seen this gull many years ago, but as time goes on we learn new things and gain more experience with odd individuals, so please have a look again

There has been some debate concerning the age of the bird, in the beginning when only seen at some distance it was suspected as being a 4th winter (5K) based on the apparently pure adult plumage with completely white tail and all adult tertials and the only exceptions being the extreme nicotine brown shawl and hooded appearance and the retarded development in bill colour. But after closer examinations the immature wash on primary coverts along with some markings on the inner primaries became apparent and it was then re-aged as a 3rd winter (4K) gull.
Any suggestions on age and ID would be much appreciated
Cheers, Kent
