Edison Bell Discs

 I like to imagine Edison was disc sound reproduction because Tesla wasn't and he could finally get ahead of him on something. Anyhow I'm sure we have all seen stacks of those very thick Edison Discs. I usually skip over them as it is hard enough getting a clean 78 nevermind a clean Edison disc. We do have Edison's and Bell's scientist to thank for the playable record. 
 

 Here is a rare pic of the Edison Disc in production.

  

An early beautiful player which appears to convert a cylinder player into a disc player. Very cool.
