Transposing viewer

[Jim Thomas <jwthomas@xxxxxxxxxxxxxx>]

I was wondering if someone might have some information on an item I picked up 
at a flea market.  It was sold as a pair of "binoculars", but knowing they 
were something else, I bought them.  It seems to be a transposing viewer.  
When looking through it, 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.  

Anyway, I have used this little viewer to look at my Kodak Stereo film strips 
before I cut them, and it gives a preview of the stereo effect, as if I were 
looking at them cross-eyed.  

Let me describe the viewer:
It is a heavy black metal thing with an interocular adjustment knob in the 
middle.  The only markings on it are two places where it simply says: EWEM.
It seems to be a well made viewer, not anything like some of the plastic 
viewers I've seen. 

I would be very interested in knowing if anyone knows anything about this 
viewer or similar viewers.  I could find no mention of anything like this in 
any stereo literature I could find.

Regards,
