you get a distorted view of the world, much like looking at a stereo
card whose images are transposed.  Things that should look like they go
away from you come toward you. - - - - <

Possibly, rather than transposing the images, it merely reverses each
image, right-to-left.  Then, when you preview your stereo film strips,
you would get, as you observed, a preview of the stereo effect, but from
the back side of the slide pair - unless you are viewing the film from
the emulsion side.

If that's what you have, it's a "pseudoscope".  If you viewed a properly
mounted stereo pair with it it would convert the image to a
pseudo-stereo image.

It sounds very useful for previewing, etc.  I have never seen one that
views a film strip.  I do have one that looks like a pair of binoculars
with rectangular barrels.  The barrels are full of prisms only with no
magnification, and I don't know what its specific purpose was.  But it's
a handsome device which came in a plush-lined, fitted leatherette case.

It sounds like a collector's prize, and a useful item to a user.
