I had not payed attention to the Kodachrome slides frame data. They
say in one of the sides "KODACHROME Transparency", "Processed by
TECHNICOLOR R" (with the circle meaning Registered Trade Mark); the
other side says "Made in U.S.A. P.701" , the number of slide in the
batch is also printed in red (f.e. 1,2,3...) and even more
interesting, it is engraved on each frame (via pressure on the
cardboard, without ink) the slide process date: The 18 Kodachrome
slides in the little box were processed in "DEC 59" (December 1959)
and belong to the same roll. I suspect some other slides in the box
with plastic frames are also Kodachrome from this batch, because it
was necessary to replace the cardboard frame sometimes, when it became
broken or jammed during the projection.
"Processed by TECHNICOLOR R", could be the explanation for the vivid
colors these slides showed when they were new, Technicolor process
evolved and improved from 1916 to give and /or to improve colors for
movies and it was also applied to improve color vividness for films of
still photography too.
