>Norman is right about the Bolex projection lens and its polarizers.  Dr.
John Hart, honcho of the  SCSC Movie/Video division, helped me replace
mine several years ago.  It is not too difficult to do once you obtain
optically flat, heat resistant, polarizing material that you can cut to
a small size.<

The projection lens is the one main problem for people acquiring this
system today. It is a small lens (about an inch in diameter), whereas most
16mm projections in the intervening years have turned to the larger barrel
lenses. It's fairly hard to find a projector today that can handle the
Bolex 3D lens.
