This piece was acquired by my Mother in mid 1960's. She was a Music Educator with a passion for piano, organ, and vocals. As the story goes, she bought this with her first paycheck, and it was lovingly cared for through her entire life. It functions, well, and has been well-maintained. I do not have photographs to help me archive all of the stops, but this is something I can get next time I am in the area. There are two numbers inside - one carved, and another stamped/inked onto the wood. I made the assumption the serial number was the carved number.
