PossHyb stands for possbile hybrid. Obvious darker than local herrings, but paler than local lessies. Worring thing is the lack of black on P5, leaving not too many options, suggesting northern tatus.

If the hybrid theory should be overlooked I can see the dark argentatus with features described by Peter!

Here´s a few more darkies:
