No, my eyes aren't calibrated that well.  ;)  But according to the
specs, for a Spicer normal Realist mount, the mask aperture is
21.5 x 23mm.  I think the window appears to my eyes to be that
size multiplied by the magnification factor of the viewer lenses.
And it is about 45mm away from me.  ;)

As real as the reproduction may be, I don't have a sensation of
standing exactly the same distance from the scene as I was when
I took the picture, and viewing it through a window that is the
size a real window on location would have been.  I still see a 3
dimensional image laid out behind a window a very short fixed
distance from my eyes.
