Be aware of the fact that this film, as well as many other fascinating titles, is available for download at the Prelinger Archive. http://www.prelinger.com/prelarch.html After viewing this film several times, I'm absolutely amazed that mere humans could have come up with such a complicated process! Even more, I'm amazing that such a huge quantity of recordings were made routinely this way for several decades, and that the resultant discs were relatively inexpensive. On the other hand, I wonder how many fatal illnesses resulted from breathing all the noxious fumes created by some of the exotic materials used in the process. Times *really* have changed! Aaron Z
