Karl Grisbaum singing bird music box. Automaton music box with a bird that moves, sings, chirping very loudly and sustained flapping its wings. Although the item is in excellent conditions, I point out that sometimes one wing does not seem to flap in the same way as the other. Sold as is. I therefore advise the buyer to view the many videos showing it in action and that best describe this automaton. The winding key is not its original but it works perfectly and 7-8 turns are enough to ensure a prolonged operation. Dimensions: height 4 cm, width 6 cm, length 10 cm. It will be packed with care and using special material to avoid breakage; insured and tracked shipping. https://youtu.be/c1VL1UfadQ4 https://youtu.be/jrAOO-TyZV8 https://youtu.be/t_gf9TZiZZw
