Gaspare,

I've those accounts too. We'll never know, but my take is that he knew exactly what he had done and that he was going to come to a "sticky end" as the books used to say. He bit on the capsule deliberately.

As for the ring, the skull stands out, but maybe they made it up specially for him ?? Like with "extra skull".

Wonder what it said inside besides the date. "H. Himmler" then signed "Himmler" ?
