Other cup mouthpiece serial numbers are not available at this time. 1980 - 1986 serial numbers are for student trumpet and cornets only. The Conn-O-Sax is a straight F-mezzo and very rare. Note: From 1987 to present, add 50 to the serial number prefix to calculate the year of manufacture. Keyed in F, the F-mezzo design is a unique hybrid between the Chu Berry and the Naked Lady with same side bell keys. These were the most eloborate Conn saxophones ever made with extravagant engraving and full pearl touches. Wonder Improved & Wonder Perfected - Elkhart IND
