Allan Griffin quoted me from Sell-3D, where I (between the 
lines) reminded folks of the fact that there _is_ a world 
outside off the USA :-), which sometimes is forgotten when 
people state mailing costs etc.

Indeed the past French practice of ignoring the stereo window 
(putting it at infinity) is over. It was partly due to the
fact 
that the Verascopes have no built-in window.

I remember a magnificent tutorial sequence by Guy Ventouillac, 
shown in Paris, which convinced the French that a good view 
can be totally spoiled by neglecting the stereo window. 
(That sequence was not for sale, so I look forward to 
Paul Talbot's slides, which I managed to order from outside 
the USA :-).)

A funny fact is that the stereo window originally was 
"invented" by a _Frenchman_: the famous Antoine Claudet. 
but he left France to work in London. Charles Wheatstone, the 
inventor of stereoscopic imaging, said in his second reading 
on stereoscopy (1852), after revealing that (Fox) Talbot made 
the first stereo photographs for him: "To M. Fizeau and M. 
Claudet I was indebted for the first Daguerreotypes executed 
for the stereoscope".

I don't know when Claudet first practiced the stereo window. 
The George Eastman house has a stereo daguerreotype by 
Antoine Claudet on its site: 
http://www.geh.org/taschen/m197601680117.jpg 
dated 1855 and portraying  "Francis George Claudet" (his 
brother?), and this pictures has a stereo window. But Claudet 
already in 1841 had a studio in London "on the roof of the 
Adelaide Gallery".
