I still couldn't believe this, so I dug around in my parts and turned up a parts caliber 35. Interestingly, it is *both* 17 ligne and 17.75 ligne!
The base movement is 17 ligne... and there's a removable spacer ring around it to bring it up to exactly 12 size (17 3/4 ligne). When I measured my cased caliber 35 to confirm the size (earlier message), that is what I had measured (It fits as a bezel around the outside of the dial). But actually the movement is not so large!
Yours has no spacer ring, but it's just a friction fit, so easily removed/discarded. I think that's enough evidence to say this is indeed a caliber 35, and that it is 17''' for interchange purposes.
So convoluted...
I will take some photos for proof.
