[photo-3d] lenses and 2D/3D combined

[dhallstead@xxxxxxxx]

Hello Fellow 3d folks,
    My name is Doug Hallstead. I'm new here so forgive any breaches 
of etiquette.
  I'm a grade 2 teacher in Winnipeg, Canada and have been taking 3d 
slides since 1964 (!)  Just a few months ago began shooting for 
prints and viewing on one of the original stereopticons.
  I have a couple of questions.

1. Does anyone know where I can buy lenses in order to build replica 
stereopticons for friends.

2. Has anyone explored combining 3d (in center) with 2d on both sides 
and viewing with the Lorgnette style viewer available from American 
Paper Optics (originally  by The Added Dimension).  This viewer has 
less magnification and therefore a wider field of view.  I find I can 
create something that aproximates natural vision since only the 
center of our field of vision is 3d and the peripheral is 2D.

Hope to hear from someone.
