If you could correct the spacing and light path problems (as the Teco
has done), the next challenge would then be to devise an advance
mechanism that would let you click through a whole roll of film
easily.  You would also, of course, have to protect the film from
scratching.

If that could be done, I'd much rather look at an unmounted roll than
use a slide-at-a-time viewer.  The viewer should, of course, position
the film and gates so they appear to be "perfectly" (whatever that
means) mounted.
