This allowed the sound, focused by the parabolic bell, to be concentrated in a compact volume and transmitted to the ear. The earpiece is spherical, also made of brass. The total height of the earpiece is approximately 11 cm. The opening at the wide end of the earpiece is adorned with a decorative grille featuring a floral pattern. No manufacturer’s markings. Items of this design were produced by a number of English manufacturers, such as F. C. Rein & Son, Maw & Son, etc. Overall good condition. England, ca. 1880.
