Not AH: roller bearing question

[joe mulqueen <joemulqueen@yahoo.com>]

Greetings,
I'm inspecting the rear wheel bearings on my old
Landrover and the finish on the races is dull gray.  I
can see the original finish where the rollers don't
contact and it's shiny.  The rollers themselves look
shiny and there's no obvious pitting anywhere.  Would
the dull finish make for a noisier bearing or imply
it's significantly worn or damaged? 
Thanks for any advice!
