Thank you! This is enormously interesting to me. I hope it will also interest the original poster, since it confirms that both the recording device and the wax blanks have been reconstructed and successfully used in recent years.recordmaker wrote:The Science Museum Journal
Here is a link to a pdf of the Beethoven project in 2014

The article mentions the set of recordings of extracts from Wagner's Parsifal made by the Berlin Philharmonic under Alfred Hertz shortly before the Nikisch recording; the first illustration in the article shows the conductor and players in the studio. I have just digitised the Prelude from this set; see http://www.horologia.me.uk/discs_1911_1925.html, third item on the page.
