The story goes that Kubrick found 2/3ds of theaters in France and Germany already couldn't show movies in 1.66 in 1971 and he fixed that by sending them 1.66 projector aperture plates which doesn't fix a thing.

I don't know how he fixed that 4 years later. I'm sure the majority of people saw it in 1.85 in it's theatrical exhibition.
I know I saw the X-rated cut of ACO with the extended speeded-up sequence shot at 2fps, in 1.85. The film script photo-book he published for which he selected the frames enlargements they certainly are not in 1.66. Measure them. I did.

Wasn't the reasoning behind 1.66 that Kubrick wanted it to have the same dimensions as paintings from the period?
