Advice please! Common Gull.

This gull was on its own near Dornock, East coast of Scotland, last Summer. Can someone help with ID? I've looked up books and because of the variation in bill colour, feathers and legs, from year to year as they age, I can't find it. Is it a juv Black Headed Gull? It has a black tip to the bill which is only visible once you know it's there....! Not a stunning shot, but has me puzzled. It would help to have your reasoning rather than a bald statement of what it is. Thanks.
