A tortoiseshell singing bird by Rochat

Rectangular tortoiseshell case with central lid. The oval lid enamel painting on the exterior lakeside and mountains on the interior brightly enamelled with flower bouquets on a turquoise ground. When activated the lid opens to reveal  the singing and dancing feathered automaton bird. Turning his head, flapping his wings and tail and opening his beak while singing a joyful song. The tortoiseshell case is in impeccable condition (wich is rare due to the nature of the material). At the end of the song the  a small turquoise-feathered singing bird hides in a opening in a pierced oval grille. This is a the fusée movement with the 3 tulips for Rochat
