The hairspring stud screw was stripped. We can see here that a prior repairer tried to get it to hold by hitting the balance cock above the screw hole with a punch in an attempt the collapse the hole. They could at least have done it on the back side where it wouldn't show.
At any rate it didn't work, the screw would not tighten. And this isn't a proper fix anyway. The first thing I did was try the different screw. That worked fine.
The balance staff, with a pivot broken, was actually just glued on to the wheel with super glue. That won't work, but it did make it easy the get the broken staff off. It practically fell out. Then I removed all the glue easily.
