Rare "Interchangeable Gloria Polytype" Musical Box by Allard, c.

No. 9558, with four six-air cylinders, two combs of 55 and 54 teeth (both complete, extreme treble tooth of left comb replaced), twin zither attachments, nickel-plated mechanism, double-spring motor, safety-check beneath the bedplate, tune-indicator, tune-selector and speed-regulator, in veneered and banded case with original finish, inlaid brass and mother-of-pearl motif on the lid, tune-sheet and cylinder storage drawer in plinth, cylinders 13 ½ in. (34 cm), overall 33 in. (84 cm), cylinders cleaned, movement in good playing condition albeit a couple of dampers in need of adjustment, four small sections of veneer loss to front of case. - Note: The so-called Polytype was a later development in the production of cylinder musical boxes, in which individual tracks (or in this case individual cylinders) are pinned with distinctly different musical effects. Cylinder no. 10213 features sublime harmony, no. 10215 piccolo and no. 10216 tremolo arrangements, while no. 10218 has a mixture of all three. As might be expected for a musical box with stylistic diversity, the program is also appropriately representative, incorporating operatic motifs by Verdi, Wagner and Bizet, ballads (including "Robin Adair"), popular airs, dances and three American titles. - Literature: Graham Webb, "The Cylinder Music Box Handbook", p. 34; W.J.G. Ord-Hume, "The Musical Box, A Guide for Collectors", p. 151. - Ord-Hume describes a Polytype zither box with 13 ½ in. cylinder by Paillard, Vaucher & Fils: "(…) the tunes were arranged in very different manners, two being sublime harmonie, two as piccolo zither and the final pair being tremolo zither".
