I could be wrong, but I don't think my RBT X3B has any built-in
window, other than at infinity.  The lenses are directly in front
of the exposure apertures as in the base XRX-3PF cameras, and I don't
think the apertures are modified.  At least not in my 'B' version
(full 18/36 exp.w/full size frames so that standard store processing
and mounting of slides works great).

All I know is that dropping the 2x2's into the viewer, and setting the 
interoccular adjustment of the
viewer at the "middle", works pretty well, even for my wife who has
problems looking at many viewers due to her slightly wider than average eye
spacing.  Her eyes, opposite of mine, are "touchy" and the images need to
be reasonably close to "correct" as not to cause eyestrain.

Keep in mind that I'm of the opinion that one can get away with murder
when looking at stereo slides in a viewer -- while others gag if the
closest-in thing is as far as 6-inches behind the window.  I like
everything, just some more than others -- rather than love'm or hate'm.

It takes hurting-my-eyes to make me not like something, and except for
extremes, it takes projection to do that.  For me.
