I added 6 more pics of the Fernhill Glaucland Gull to my eBird checklist:

I believe that the short/narrow bill of the Fernhill bird is smaller than that
of the smallest barrovianus Glaucous Gull bill.
The primary projection seems long enough for Iceland. General size also works
for an Iceland male.
The head is awfully rectangular, in particular when the bird is resting. That
said, that may still work for Iceland. The small eyes create an impression that
the bird is large headed pointing away from Iceland.
