S3D FS: B & L Ortho Fusor, and 15 Vectographs

[Peter Abrahams <telscope@xxxxxxxxxx>]

For sale: Bausch & Lomb Ortho-Fusor, visual training kit from 1941.  Uses
vectographic photos in layers on top of foil to give a 3d print.  5 photos
of people & landscape in a 4 inch by 6 inch booklet, each photo has a
different amount of divergence & has overlays to aid in converging on the
photo.  These 5 range in 'difficulty' & the most extreme are hard to view;
it is claimed that this viewing exercises the eyes.  I've seen about 20 of
these kits & all have varying degrees of fading, this one is the best I've
seen: just slightly faded & all photos have a good amount of contrast.
Includes two identical instruction booklets, 2 plastic polaroid spectacles,
and one glass polaroid spectacles in a nice frame, but all spectacles have
lost most of their polarization.  All in excellent condition, box just
slightly worn at edges.  $30. includes shipping in the US, but I will wait
a few days to see if the package sells (see below).

15 vectographs, 3.25 inches by 4 inches, for navigation instruction -- wire
drawings of celestial spheres, globe projections,  etc.  They have a fair
amount of detail but are schematic drawings. We projected them at the
Cascade Stereo Society, they completely 'violated the window' and the
spheres looked suspended in the room.  6 are in very good condition, 7 are
fair to good (slightly faded but all detail is there & they project & view
well), and 2 are faded with loss of detail.  
$190. including shipping to US.  $200. for all the above including shipping
to US.
