Here’s something you don’t see everyday…  a collection of Recordgraph Amertape recordings from WW2: http://www.ebay.com/itm/221723707133  

The seller also has a dedicated website about the collection that is up for sale with audio samples: http://d-dayrecordgraph.com/Home_Page.html

Apparently the seller had them transferred by Poppy Records in the UK, who custom built machine just for this project: http://www.poppyrecords.co.uk/other/recordgraph/recordgraph.htm

Not sure about that asking price, but nevertheless a fascinating audio artifact from a pivotal moment in the world’s history that I thought was worth sharing.
