If the Fig is not what the label say it is,then it is usually a hybrid.
That fig is not Mission,and I doubt a lot that it is Peter Honey.
I would label it unknown,till you grow a Peter Honey 6-10 foot from it on the same level,eather south or north of this one so it catches the same light,and then you can compare to it and see if it is identical or not.
Till then keep it if it taste good enough for you to like it ,or discard it if you do not like the taste.
