The sapphire stylus is just under 9 mil.
I have a calibrated microscope to measure and inspect them.
If this needle does not fit your machine because the shank is too big or other issues, just let me know and I'll ship you a different type of needle. I have different types of shank diameters, lengths and collars.
These are for playing 'sapphire-cut' vertical recordings, also called hill-and-dale. This stylus has tested excellently on the smaller-sized 90rpm centre-start discs up to 11½".
The stylus will not work on any vertically-recorded, fine-cut groove of 'V' form such as Edison, Marathon, Aeolian Vocalion and the earliest Gennets, Okehs and Grey Gulls.
Provenance:
A well-known collector of early recordings, Edouard Pecourt, bought old inventories of sapphire ball stylus needles in Paris, France, during the 1950s and 1960s. In 2002, he sifted through these needles and examined them individually for quality. This item is one of needles he inspected and approved. It is brand new, never used.
From the UC Library website: "Edouard Pecourt was a Parisian record dealer and collector who owned
La Boîte à Disques
in Paris from the early 1950s until he emigrated, along with his collection, to the United States in 1986. Pecourt’s extraordinary collection of over 3,000 cylinders and 18,000 discs was acquired by the UCSB Library in 2010. The Library’s collection of cylinder recordings now numbers over 12,000 titles, and outside of the Bibliothèque nationale de France, it contains the largest collection of French cylinders in a public institution.
