The B-17 display model on the stand has (when activated) two-speed spinning propellors, a light in the nose, and numerous aircraft sounds (such as humming aircraft engines, propellor start up noises, and the sounds of firing machine guns). The clock/model is all in full working order. The B-17 animation can be activated manually by pushing a button on the base unit or it can be set to start when the alarm goes off. Also, the clock unit swivels so it can be positioned to be seen regardless of which way you want to display the aircraft. The clock requires four AA batteries (not included). The clock is approx 18" x 12 1/2" x 9" and it weighs 1.24lb. The clock is in a good, used condition with light wear on the clock, missing decals, and some battery residue in the battery case. Please see the images as they are part of the description.
