Probably by Cuendet, No. 10449/204785, with 2 parallel counter-rotating 8-air cylinders, crank-wind quadruple-spring motor with intermediate gear, twin combs of 62 teeth each (complete), engine-turned zithers, butterfly-wing governor, tune-sheet and "Tirelire" tune-indicator engraved "Brevete No. 7298" and dated 1894, in grained case with rosewood-veneered lid, recessed floral inlaid panel, drawer for the crank and later ebonised stand with turned legs, wd. 35 ½ in. (93 cm), cylinders 13 in. (33 cm), one treble tooth nicely replaced. – Arthur Ord-Hume attributes the first patent of a 'duplex' musical box to Alfred Junod in around 1887, with double-cylinder machines by Charles Paillard, Mermod Frères, Ami Rivenc (and presumably other makers) appearing on the market soon afterwards. Built to increase volume and resonance in the same way as a single-cylinder "sublime harmony" musical box, the duplex musical box featured a pair of identically-arranged cylinders playing simultaneously on two identically-tuned combs. The Symphonion Musikwerke of Leipzig sought to create a similar effect with its triple-disc "Eroica" musical box. A mechanical music spectacle in restored playing condition! – Literature: Ord-Hume, "The Musical Box, a Guide for Collectors", p. 147; Q.
