btw whats hidden on the forehead? Might be an actual cause. When I noticed, at first I thought it was a reich eagle, but with the bottom reef cut off... like symbolizing the eye being the reef and swastika. There are two types of eagles, one with wings extended and then the other that this looks more like with the wings half folded and down.
Edit: oh and that neck tattoo.... the left one.
That looks like 884 on one of those old style life preservers...
