Even if it was B.P. originally, that's not where you'd expect something to crack. I know hindsight is a great thing but those square corners the crack started at seems like an obvious place when you see it now, but it's worrying if you have an old gun you'd like to have re-proofed.
I'm guessing it was off face after their proof loads and not before wink
