I bought a couple of 41x64mm achromats from AS&S recently, and think
that they hold some promise. Not 46mm, but definitely a bigger field
of view than the 84mm lenses.

They looked like they were removed from equipment, in that there
was a black -something- on the edges of the lenses, but the front
and back surfaces were clean and in great shape.

I plan to talk to Alan (Hi, Alan!) about the possibility of a
second "lens board" for the MF viewer kit, or see if they fit
the existing board (it has a 40mm dia. opening, not sure if Alan
designed in any "slop" room s.t. a 41mm might fit).
