Any consideration on some other crafts to have Antique restore options: Jewelry, Art, Tailoring, maybe even Brewing are the most obvious that could have some antique restore craft options like Woodworking does at higher levels?
Jewelry - Polishing and restoring older pieces.
Art - Restoring old paintings or other artworks.
Tailoring - Could be a Vavardi specialty to restore vintage clothes as secondhand sales are mentioned in their helpfiles.
Brewing - Decanting old, rare vintages to make them properly drinkable.
Next to all this, a way to boost the usefulness of Forgery could be producing components for some of these things that are indeed, fake. It could represent producing fake letters of provenance and the like.
