1771's ills

Yes, there is a problem w/the boiler, and it fits in with the NG boiler problems too, so there's the NG content!

At the point where the barrel course intersect the front of the firebox plates (knuckle? I can't remember the tech term) there is an applied patch. This is an area prone to cracking, so that's not so unusual, but the CA state boiler inspector doesn't like it. I have looked at the patch, and it appears very proffessionally done, but I don't have a clue as to what the stress calculations show, or what ultra sound might show. The rumor is that the Boiler Inspector doesn't like riveted boilers at all, so. . .
It does make removing the jacket and inspecting 1727's boiler to see if the same patch was applied a very high priority for any operational restoration planning. The records we have uncovered so far don't indicate patch work, but it wouldn't be the first time the existing records don't match the existing artifact!
