Aggie, I am far from an expert, but it looks like a pretty simple repair. As others have suggested use Acraglass, and I’m pretty much restating what has already been said. It is pretty simple to use. First take a small chisel and clean up the inlets. Clean out the screw holes with a small pointed needle file. Apply a good coating of release agent to the metal parts. Put in acraglass and let cure. The acraglass will have filled the screw holes which is good. Once cured carefully put screws back in coated with wax and all should be good. Just be sure to tape off area around inlets to prevent the epoxy from getting on the surrounding finish as others have said. Will not be difficult to do, and you’ll have the satisfaction of saving the original stock.
