120 format stereo cameras

[Brian Reynolds <reynolds@xxxxxxxxx>]

While looking through John Saddy's lastest View-Master auction hoping
to find a View-Master camera and cutter I came across two cameras that
interest me, and I was wondering if anyone could tell me anything
about them.  I've already done an Altavista search and not come up
with anything useful.

The first is a "CORONET STEREO 120 CAMERA" listed as mint but a low
quality camera with plastic lenses.  The estimated price is $90.  The
other references I was able to find on a Coronet stereo camera said
that it took 127 film.  Was there a version that took 120 rollfilm?
In mint condition, with box and viewer, is this camera worth $90 as a
user, not a collector?

the other camera is a "HEIDOSCOP STEREO CAMERA 6 X 9 WITH LEATHER CASE
AND HEIDOSCOP FILM PACK BACK" in VG+ condition with an estimated price
of $175.  I know the Heidoscop was a plate camera, and that there was
also a rollfilm back for it.  Does this camera take 6x6 pairs, or
6x4.5 pairs as the lot desciption suggests?  Is this a good user
value?

For any higher than this I'd probably buy a Sputnik from Joel.
