Here's an Ansonia "Bagdad" wall clock that was found at an estate sale approx. one year ago. It is approx. 50" high and has the double-mainspring time only 8 day movement. A similar clock can be seen in the Tran Duy Ly book on page 182. They also supplied this clock with 8 day double-weight time only movement and 8 day time and strike spring movement.
