Thank you for viewing. YAMAHA Nikkan YTR135, Key B♭ M bore, bell diameter 127, nickel-plated Pistons move smoothly without sticking! Nickel silver feels heavy, but it actually allows for easy airflow and a light, comfortable playing experience! It's also used in models like the Conn 38B, and YAMAHA's unique nickel construction provides reliability, allowing for high notes without feeling thin and excelling at mellow tones! The nickel plating on this trumpet is well-preserved, ensuring good airtightness and long-lasting use. The hard case is in good condition, with no issues with the hinges or handle, and no odors or stickiness. This is a great trumpet. Please consider it at this opportunity.
