No doubt it's horrible brazing. It looks like they burned the bb shell itself up by the guide, which is a good trick.
Would be interesting to know if they got penetration under the guides. If the shell is any indication, the answer would be no. But I wonder if it was different people, one of whom should never have lit a torch.
I see what Doug is saying about inside, there is a fairly sharp line around the golden glob. Probably got filler in there by mistake.
that would be a good name for an award for bad brazing, "The golden glob award"
