[Milsurplus] Re: [ARC5] NPC: A Tune for Pearl Harbor Day

[Mike Hanz]

I thought the mass produced records of WWII were shellac - I know I 
accidentally broke more than one when I was a kid, much to the 
irritation of my parents.  Originals were aluminum disk coated with 
black lacquer, or at least that's what the ANQ-2 disk recorder uses.  
Here's what one site sez,

"From 1897 onwards, earlier materials were largely replaced by a rather 
brittle formula of 25% "shellac" (a material obtained from the excretion 
of a southeast Asian beetle), a filler of a cotton compound similar to 
manila paper, powdered slate and a small amount of a wax lubricant. The 
mass production of shellac records began in 1898 in Hanover, Germany. 
Shellac records were the most common until the 1950s. Unbreakable 
records, usually of celluloid which was an early form of plastic on a 
pasteboard base, were made from 1904 onwards, but they suffered from an 
exceptionally high level of surface noise."
