What is the history of a William Knabe piano serial number 153595?
Based on the serial number, the piano was built in the early 1890s. The “gold medal” means very little. Medals were given to the major piano makers during world fairs, etc. but the practice was really more of a marketing gimick than anything else. That being said, Knabe was one of the four best american piano makers at that time (including Steinway, Mason & Hamlin, and Chickering).
