That would be good braze, that was as strong as the steel. You know that isn�t possible, right?

Smith�s were built with a corrosive flux used at barrel assembly. If corrosion led into the chamber, and allowed combustion gasses into the area between the rib and the tubes, that might explain what we are seeing in the black area. It also might explain why it looks like a 12/28 burst, without a clearly defined ring bulge.
The chamber wall appears thinner, from what I can see in an internet photo, then can be explained by stretch to elastic yield, but, it is only an internet photo, so far.
But, it is the most worrisome thing I can see.

Best,
