S3D Stereo Projection Lenses

[Tony Alderson <aifxtony@xxxxxxx>]

I've uncovered an item in my closet that might be of interest. It is
labled "VIEW-MASTER projection lens in barrel to fit StereoVivid." 
These are plastic lenses (at least two element) in red plastic barrels.
The ends have been turned down and threaded to fit into custom-made
aluminum barrels for the Stereo Vivid projectors. They appear to be
about 2 inch focal length. There are some slight marks on the lenses,
but not enough to significantly degrade

I picked these up when Stereovision was clearing out their warehouse
some years ago. I tried (once upon a time) to fit them in my TDC 116,
but the assembly is so long (almost 5 inches) it seemed to interfere
with the blanking shutter in the housing. However, I think they could
fit in the TDC 716, which has the shutter in the carrier, instead of the
projector. About that same time I made a trade for some 4 inch lenses,
so these ended up in limbo. 

Take a look at:

Since I never went far enough to confirm these actually work, I'm
offering them "AS IS."  Asking US $20 plus $5 shipping.
