The Sawyers Bi-Lens doesn't use a curved mirror.  It has an arrangement of 
front-surface and half-silvered (beam-splitter) mirrors that direct the 
same image to both eyes.

The Realist Real-a-rama uses a curved mirror, but it's not lighted.

I've been thinking of doing this with some slides shot with a Vivitar Q-dos 
lens.
