That should buff out...
Well, the outer wing just bolts on to the inner stub wing outboard of the engine nacelle. See the story of the DC-2 1/2, for instance.
I was surprised to see a DC-3 being repaired with a shiny-new wingtip after the old one had been mangled in an argument with a telephone pole guy wire at Miami International about 30 years ago. The mechanic laughed and told me that there were warehouses full of DC-3 spares because so much stuff was produced during the War. If that still includes wings then this might not be so bad. Fixing the engine might be more troublesome.
