[photo-3d] Stereoscopic card viewer

[pennywise@xxxxxxxxxxxxxx]

I made a very good quality viewer for stereo cards with achromats 
bought from   www.surplusshack.com
This site sells surplus optical devices including hundreds of lenses.
Last year I bought a beautiful matched pair of f 2.8 xenars 35mm 
and I think they were $6 each (New)
The man in charge is "Fred" and he did have some freestanding 
stereo viewers in brass with every adjustment you could think of 
with a pair of 3 element optics which were ex USAF for $12 each 
including leather case.
Maybe he still has some?
