mystery viewers

[P3D <Cghon@xxxxxxx>]

I have two stereo viewers I'd appreciate some info about.  One takes
a transparent slide (probably hand-painted) of about 2 3/4 in. x 5 1/4.
There is a hinged top with a mirror; a telescopic-type viewer with
a focussing knob on the right side, and a lovely marbelized wood 
pattern on the viewer.  Perfect condition, found , I believe, at an
antique shop. Problem:  I have no transparencies for viewing and
would like to find at least one!  The 2nd viewer is similar, with the 
ground glass back (no hinges) and a mirror in a hinged door on top.
The viewing front has hinges and takes a pair of heavy glass lenses 
glued in.  (Poor condition -- thanks to our parrot who started chewing
on the wood -- but can be renovated.)  No slides or Holmes-type card
would fit this one either. They both have a divider in the center
between the viewing lenses and the ground glass in the back.
I don't want to sell these, as I believe they are quite unique, 
but I would like some identification!
Thanks,
Carole
