I picked up another basic restoration project; an old Wade & Butcher with what appears to be yellowed ivory scales. They're extremely thin and fragile looking but theres no major cracks just a few tiny chips on the wedge end. Someone "scratched" their name into it (lightly) that i'd like to sand out and then clean them up with some polish. Any suggestions? I was hoping the Maas polish would work well at removing a bit of the yellowing but wasn't sure about on ivory.

(Sorry, pictures will come tonight when i get home)
