I did send an email yesterday to Nikon, but used the S/N from the Exif file. As suggested by another Hog, I finally found it barely visible on the aperture ring: 208060. I'll update my email to Nikon with the correct number and see what they say. Thanks for all the advice.
Good for you! You found it and it's a nice one, easy to remember.
