This is a small mechanical cuckoo clock from Engstler, Germany. Engstler was founded in 1952 in Villingen, in the Black Forest region, the heart of the German clock industry. They are a renowned clockmaker, especially for their wooden cuckoo clocks, and are considered one of the top five in the world. Before listing, I wound the clock and confirmed it ran for about half a day. The bird's movement and the pendulum's operation have been confirmed, but the time accuracy over a long period has not been checked. The size is approximately 12 x 12 cm. Includes the original box and screws. This is an old item. Please understand that this is a sale of the item as is. Thank you for looking.
