From a local estate, this little Reuge enamel music box measures 2 inches tall, 4 1/2 inches wide and approx. The enamel is in excellent condition and I don't think it was played very much.
I tested it and it works. It comes with the original instructions that tell you how to operate it and what not to do. The instructions say to never handle the bird, never lift the door and do not force the bird down. If the door does not fully close, wind the mechanism again. The instructions say to first wind without force, then push the gold lever on the front to operate.
The door will open and the bird comes out to sing. The item "Vintage Reuge Singing Bird Automaton Enamel Music Box Very Nice Condition" is in sale since Friday, February 26, 2021.
