L100 Grill Vaneer or Solid Walnut?

Hey all, does the L100 grills the same walnut vaneer or are they solid wood?
I am looking to refurbish them and wanted to make sure I don't sand through the vaneer.

There are so many different version of this speaker, you should be more specific. On the original version from the 70s, the trim at the edges of the foam is solid wood.

Thanks for the reply. It's the L100 Century (L100A).
I am guessing these are solid wood trim as well?

Yes, still solid wood then.
