May be small areas of wear to wood from being moved & stored in box for all these years.
Chains have some loss of finish color (see pics).
Wood finish on the roof appears to be a little dull.
Bottom back of clock: 2 circular pads are deteriorated and coming off if you rub on them. May need to be cleaned off upon receipt of clock.
I took close up pictures of any areas I thought had minor wear.
See all pictures for details & reach out if you have any questions.
