Collapse and restart of Berliner's Gramophone in a nutshell

[Starkton]

I am very sorry that these are reproductions. Thank you to all participants in the discussion. At least we have learned something. I have only these two and it was no great financial loss as I didn't get it in a steady battle.

It is a greater loss for our historical knowledge because it raises the question how these early needle packs really looked like.
