22 old Edison records. These are all in good shape. They play on the Edison disc phonographs and are also known as diamond discs. They were in production from 1912-1929. They are about 1/4 thick, about 4 times as much as regular vinyl finals. They are made of phenolic resin (Bakelite) on a core of wood flour. They are very stiff as compared to vinyl.
