Dating stereo views

[P3D Charles D Hotchkiss <revcdh@xxxxxxxx>]

I have a large box of stereo photos, mostly home-made, but with a few
Keystone cards thrown in. These pictures, along with a Holmes style
viewer have been in the family for years, but nobody seems to know who
took the pictures or when they were taken.
Mostly they are vacation-style pictures, taken in various places, I can
identify scenes in  Ohio, Indiana, Kentucky, Illinois, Iowa, Colorado and
Wyoming.  It is more difficult to place them in time, other than between
1010 and 1930

Over the years I've looked at them a million times, but only last night
did I notice that one of the cards was apparently some sort of promotion,
because it had the following copy printed on the back:

"Print showing the size and quality of negative made with
 STEREO KODAK --MODEL NO.1 with kodak Anastigmatic lens F. 7.7 and
quality of print made on velox paper.  Mounted with Kodak Dry Mounting
Tissue"

 Does anyone know anything about this camera? Knowing when the Kodak
Stereo No. 1 was popular would greatly help me date the pictures and
perhaps help me  identify some of the people in the photos. 

By the way, the prints are in surprising good shape for their age,
especially since there storage has been less than archival. and that old
Kodak dry mounting tissue is still  holding tight. 

Thanks, 
Charlie Hotchkiss
