Selling this wonderful Conn 24B Opera Grand in great condition! Recently serviced by my technician, plays great top to bottom! These older Conns are difficult to positively identify, but it is near certainty an Opera Grand due to the following signs: Serial number is 189,9XX. Has a 4 5/8 inch bell, .438 bore, gold wash bell, engraved, and lovely silver plating with small wear marks. This horn plays great with fantastic tone, notes pop very easily! Valves are extremely smooth and responsive, all tuning slides work great. No mouthpiece included. Ships fast, fully insured, and signature required via UPS Ground. Let me know if you have any questions, thanks for looking!
