They never did.
Plastic plugs hid them well though
Bridge reglued and now being plugged with wood.
Glued this joint that was split at the glue joint. The longer the joint was open the darker the line will be. Could have been invisible had it been repaired right after it happened.
Look at the bridge...
Glued the broken pieces
Then reglued it back to where it will live for a long time, hopefully.
...despite 3 bolts (they never does the job well).
The unsuitable solution
Causing more harm than good.
Time to remove the stressed bridge.
Clean up for a solid glue joint
Patch the bolt holes, prepare the gluing surface for regluing.
Bridge reglued and damaged top touched up.
Nice tight fit
Badly damaged side needing an impossible invisible repair
Make it strikingly visible then!
