I suppose they did this with Jaws 3D (or did that come with red/blue glasses?) and still holding out hope that someday the 3D short from Disneyland, Captain EO, will see a home 3D release...
Regarding Nutie Cuties, nothing has been converted, it is all native 3-D material. The Coppola color 3-D footage in "Bellboys and the Playgirls" amounts to a few minutes only - it was spliced into a German black and white flat/2-D film made a few years earlier. The version with the 3-D sequences was released back then in anaglyph form (from what I've read),
"Adam and Six Eves" was the final film shot with the Natural Vision system, but it was never released in 3-D, going out flat only a couple of years after production. This is the first 3-D release!
The burlesque short, while shot in discrete 3-D, was almost certainly released in anaglyph form.
(Not sure why you brought up Jaws 3-D, but that was shot entirely in 3-D and was polarized 3-D only in theaters in 1983, like the vast majority of all 3-D features ever. Anaglyph has only been used in rare exceptions, and then usually for 2-D movies which had short 3-D segments inserted, such as "The Mask" or "Freddy's Dead", etc.)
