637 Dunno about chestnuts, but definitely a wooden spoon. SWMBO has a
few
very similar ones.

I had a difficult time getting a decent photo of this one, it's not a spoon,
the head is round like a ball. I clarified the description on the web site.

There are no correct answers for it yet. It's probably at least 50, maybe
up to 150 or more years old.
