Having communicated with Mr. Price, it seems that he old DVD was field enlarged, which means that 1.85 should be fine.
That is his opinion.
And I believe him.

After comparing the ratios on Beaver, the 1.37 is definitely a field enlargement, but I also find the 1.85 too tight.
I much prefer the film in 1.66. Personal opinion.

I believe that documentation is a good starting point, but prefer to mask at potential ratios, and see which works best for the film. My preference on Dial is 1.66, which is the same as Rear Window, which was released 90 days later.
