"Keyboard from a Schulmerich Carillon Bells which was a type of early synthesizer. It is in an oak case which measures 17-1/2" by 12-1/2" by 6-3/4". There are two octaves or 25 keys. There is a contact switch for each key and some other electronic parts inside. I believe this dates from the 1940's. It is marked: A Product of Schulmerich Electronics Inc. Sellersville, Pa. Any mad scientists out there need the start of a cool project?..."
Update via daden in the comments: "it is not a kind ofg synthesizer it's a remote for the motors of the carillon hammers..."
