As an old RCA Victor Record Division employee, the film "Command Performance" narrated by Milton Cross has always fascinated me. It is a documentary on how RCA Victor phonograph records are made, specifically shellac 78 rpm records. An excellently photographed tour through RCA's Camden plant in the 1940's showing most details of the process. It is all deadly accurate and should answer virtually any questions about how it was done when wax was the master recording medium of choice. I've had a poor and incomplete VHS copy of this film for years, and was looking for a good copy of the original film, but I recently came across someone selling this film on EBAY. It is an excellent DVD transfer of the film, complete from main opening title to closing credits and end title and can be had for $7.99 plus $2 shipping (even to Canada). RCA Victor record plant film on DVD: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3594662591&ssPageName=ADME:B:SS:US:1 (Here's a TINYURL in case you can't click on the above) http://tinyurl.com/2zkoe This seller has 18 pages of other "industrial/documentary films on EBAY and repeats them regularly, so bid the minimum $7.99 and you'll probably get it for that, otherwise wait for the next repeat, or pay his "Buy it Now" price of $9.99. I have no affiliation with this EBAY seller other than I bought one from him. His product is excellent, and delivery is prompt. ...
