With nothing left to prevent the right-side striker bushing from rotating and floating back and forth, repeated blows from the hammer caused the striker to become quite deformed. It comes as no surprise that the lockplate screw slots were also damaged.
The strikers, the bent right striker had to be cut in half to remove it from its bushing.
The stock damage
Once the finish is stripped from the head area and the soaked oil is removed, the stock repairs could begin. As always, the repairs are performed by replacing bad/damaged wood with new, not "glass bedding" bodgery.
The repair after fitting
The lockplate screws were made in the usual fashion.
The finished job, note the beautifully chiseled fences.
