I've gone back through both the QuadList thread that goes back several years, and also the AMIA-L (Association of Moving Image Archivists) to find some past discussion.

John Gledhill at Bitworks.org posted a sample of Lenticular film during a discussion about how to tell ordinary black and white from black and white vintage Lenticular Kodacolor when spliced into the same reel.

Along with the link, John advised:
Check the shape of the lenticular marks as they cross the women by the  foliage http://www.pbase.com/filmworks4ever/image/133995785

I remember seeing some Lenticular color film after recovery, but I can't recall where or when.

Googling "Kodacolor Lenticular Film" brings up a number of references, including links to clips, and this useful document that tells what to look for, and outlines a digital color recovery process.

Scroll down this linked page about half-way to see some magnified examples of original Kodacolor Lenticular film are shown on this Vancouver Archives webpage:

Film Technology (FilmTech) on Cole Ave. in Los Angeles did a transfer to film for the archive.  Call Zac Fink to get more information.

Here's a 720p clip from LA-based Periscope Films stock footage archive, which used a service provider's proprietary system to transfer the footage:

So keep an eye out for some funny-looking black and white movie film that has an odd vertical stripe pattern in it.  You may have some color lurking therein.
