>What's a Graflex Stereo 35mm like? I can't find it in any of my books.

Cheap Realist-format camera from the 50s.  Below average results.  I have
seen soft images with flare from this camera.  One lens is focused at
infinity, the other at a close distance so no focusing is needed !?!?!
Has two lenses and should be available for under $100.

>And last of all, what exactly is a Realist ST-61 viewer? Is that one of the

Complete list of Realist stereo viewers:

ST-61 or 2061:  Red-button, oldest (1947), classic, a beauty, achromats.
ST-62 or 2062:  Green-button, AC/DC, achromats.
ST-63 or 2063:  Handi-viewer, cheap, first achromats then single-element.
ST-64 or 2064:  White-button brown case (usually), same as red-button but
                with single-element lenses.
ST-65 or 2065:  Variation of green-button but with single-element lenses
                and only AC.  I have not seen any green-button viewer with
                single-element lenses but Ron Zakowski says they are around.

The next "Inside 3-D" magazine will have an article on single vs. double-
element lenses, which viewers have which, how to tell them apart and what
it means in terms of optical quality.  Check with Dalia for subscription
details.
