Although described on the lid as Système Michaelis (which applied to the Neophone records with their unique hill-and-dale recording for steel needles), this device appears to be a straightforward hill-and-dale system, using conventional phonograph floating heads, and is apparently identical to the Edison Bell 'Eureka'. Indeed, the Edison Bell name is stamped into the metal, although some five years separated its appearance under the Neophone name in 1906 and its resurrection under Edison Bell.
