I was wandering through my hard drives and came across these images that I've had for ages.

In case you're not familiar with the device, they were made by De Oude Delft in Delft, Holland. It's the same company that built the big Delrama anamorphic attachments for Technicolor's Technirama process.

Walter Siegmund Interview

Todd-AO - Distortion Correcting Printing Process

Internet link:

American Wide Screen Museum

 
Rather than using cylinder lens elements, Delft used curved mirrors in sort of a periscope arrangement. The function of the Delrama II was to project a curved image just like the curved Todd-AO prints did, except they did it for CinemaScope type 35mm prints. And it works. When projected on a flat screen the image forms a mild arc but when projected on a deeply curved screen from a very high booth the image conforms to the geometry of the screen.
