The bridge was re-glued before, by another technician.
4 screws were inserted to reinforce the job.
However, the glue failed again and the screws did their job,
but by pulling the soundboard head-wards (see the buldge against the light).
The 4 screws
The screw holes were plugged with ebony dust and bridge re-glued.
Couldn't find the photos for them though.
