Gunbugs makes a great point about the OP; unfortunately many do not read or forget the statement of the problem, nor do they read all the subsequent comments.

I still say that for a 100 year old metal part, with unknown history of how many times or with what ammunition it was fired, to fail.

The thin areas that broke out, have "hidden" sharp corners on the underside, a favorite place for fatigue cracks to begin.

With no pierced primers and what is a fairly common failure mode- the cause for the failure will likely never be determined.
