Den,
the top three you posted look good and there are some good photos out there as well. Tom Wittmann showed 2 or 3 at the MAX Seminar in 2015 that were very clear. But in watching the forums and reading other documents, I see blurred photos that are not saying much. Particularly when it concerns SS daggers.
I agree that seeing that early hanger is a good sign, but one of those types of hangers is not proof that the dagger is a prototype. For some reason that style, which I call "dog lead clip" was favored early but disappeared later.
