Well, I bought this figure on ebay and received it today.
Though I am by no means an expert, it really does look 100% legit in real life.
The head is a perfect, tight, snap-on fit on the German soldier body and looks completely professionally made, not like a custom job at all.
The figure has magic marker letters on the back, as we've seen in other prototype images.
The likeness is fairly remarkable up close to the character from the film.
I will say the hairline possibly looks SLIGHTLY too short, as discussed. But we've seen far worse gaffes from Hasbro before in terms of accuracy.
I dunno, I cannot vouch for the origins or legitimacy of this figure. But I will say it at least looks ENTIRELY convincing.
I will post pics tomorrow......
