transposing viewer

[Michael Kaplan <mkaplan@xxxxxxxxxxxxxxxxxx>]

While I can't identify this viewer from the description, it sounds like a 
viewer designed for Tru-Vue type stereo film strips. These were positives 
printed from negatives, where the images were transposed in the printing 
process. Transparencies shot with a conventional stereo camera would be 
"un-transposed" if you try to view them without cutting and mounting. 

The only viewer I know of that actually transposes images (through a set of 
prisms) is that made by Leitz, as part of its Stemar system.
