This is a vintage trombone purchased in the 1960s (Showa 40s). Nikkan later became Yamaha. There are no dents. Includes the body and mouthpiece. The case has peeling on the surface due to deterioration. Please understand that this is a used/vintage item. Although it is a vintage item, I think it is in very good condition for its age. Serial number: "6704054" ◼️Founded in 1902, Egawa Gakki Seisakusho later changed its name to Nippon Kangakki Co., Ltd. (Nikkan). The "Nikkan" brand was used in parallel until "Nikkan" was absorbed and merged into "Yamaha" in 1970. #Nikkan #Yamaha #Wind instruments #Yamaha instruments #Orchestra #Brass band #Musical instruments #Brass instruments #Vintage #Antique #Trombone
