[OldRestorer]

Pop off what trim and molding you can. Noting that was poorly re-glued. For the back edge where the lip is pulling away, Inject some wood glue and clamp. It looks like there is missing trim around the arch. You can add it back on or I have seen people remove what was left and match the color of the underwood... Not a real true restoration step though...

PM me your address.
I'll send you the knob you need..
