A good Charles Bruguier singing bird box with fusee automaton movement. The tortoiseshell case with hinged snuff ( or key) compartment to the rear of the box. The gold lid is finely hand painted in enamel with an excellent alpine scene with a mountain in the background, a lake with sailboat in the forground and a Swiss Schloss to the left. The key wound chain driven fusee movement working the bellows & driving multiple cams that on sliding the operating lever to the front, the lid opens and the bird pops up, sings his head off and 1/ turns its head from left to right, 2/ flaps the wings and finally 3/ pirouettes left and right. On completion of his 20 second performance he drops through the superbly pierced silver gilt grille and the lid closes after him. All fusee movements allow the bird a longer performance than the later spring barrel movements but more importantly one extra manipulation, the movement of the head from left to right. 3.75 inches wide by 2.5 inches deep and 1.5 inch high ( 9.375 cms by 6.25 cms by 3.75 cms).
