What is the age of a newman bros pump organ with the serial?

To determine the age of a Newman Bros pump organ based on its serial number, you would typically need to reference specific databases or historical records that provide information about the company's production timeline. Newman Bros was known to manufacture organs primarily in the late 19th and early 20th centuries. By cross-referencing the serial number with these records, you can estimate the year of production and thus the organ's age. If you provide the serial number, I may be able to guide you on how to find this information.
