This is a 1926 Chickering grand piano with an Ampico Model A player mechanism. It is a 5’6″ grand with a walnut art case. This is an example of a reproducing piano, which differs from an standard player piano in its ability to vary the note dynamics (volume) as it plays.
The roll mechanism and volume and tempo controls are located in a pullout drawer under the keyboard.
Everything is controlled pneumatically with the exception of the electric motor that drives the vacuum pump. The pneumatics are located under the main body of the piano.
