Any of the members here own one of these BA records for the machine, or did they play at a different speed than normal BAs?
Rubber or celluloid (I can't tell the difference by feel) was used in a very limited way in later Berliner 7" discs, Zonophone 9" discs, and even a few International Record Company (Auburn) 10" pressings.AmberolaAndy wrote:Unrelated to this discussion: Zon-o-phone discs used rubber in 1900?

However, and more to the point, this isn't a "company" advertisement. Foster Brothers wrote up the copy and may well have used language they thought their clientele would better understand. Note too that the illustration is of a Berliner "Improved Gramophone," so the Zonophone nomenclature may have been borrowed from Frank Seaman's brief use of it to promote the Berliner product. Zonophone machines didn't appear until April 1900, and Zonophone records didn't appear until after that, so if this ad is dated prior to April 1900, it was definitely hawking the Berliner products.
