P3D Verascope Jules Richard glass stereos

[John Bradley <JB3D@xxxxxxxxxxxxxx>]

Andy Burr asked about Jules Richard stereos.
I waited for someone more knowledgable to
reply , but in the absence of that I'll offer
a few notes. 
The format is often referred to as 45x107,
and surprisingly that size endured in to the
modern era. For example the Vistascreen / 
Weetabix/Weet-bix/Liptons stereocards were
all produced in this format in the 1960's.
Jules Richards first camera of this format,
which also doubled as a viewer , was 
produced in 1893 and was known as the Verascope.
There must have been millions of amatuer glass
slides produced in this format. I have seen many
thousands , and bought some of them to view in
my Taxiphote automatic viewer.
Bruguiere produced several hundred sets of tourist
views in this glass format , before changing to two
different plastic slide versions , and then a colour
7 sprocket transparency version.
A French enthusiast has produced a two volume 
illustrated guide to Jules Richard's work.
Andy asks about value of sets. As always this depends
on subject matter and condition. I have paid 2 to 
5pounds a set for standard tourist views, rather less 
for an amatuer collection of views of native Americans 
circa 1920, while I sold five single risque 
(very risque) slides circa 1925 at Christies for about 
400pounds. 
As always Paul Wing's book is a good source of information.
I'm using a new mail system so apologies if there
are any formatting problems with this posting (and please
let me know)
Kind regards,
