This King 3BF tenor trombone, serial number 435089, was built in 1970 during the Eastlake, Ohio production period. While it shares the same design and dimensions as standard 3B models, this example is a rare variant featuring nickel silver plating over yellow brass. The plating is protected with lacquer, which prevents tarnish and keeps the horn’s bright finish intact over time.
We performed a full professional shop service here at The Brass Exchange, including a chemical bath, valve servicing, and slide alignment. The horn has no dents or dings, and both valve and slide are in proper working order. The .508 bore with F-attachment makes it a versatile choice for commercial work, jazz, band, and any player looking for a responsive small-bore horn with extended low-range capability.
A brand-new King 3BF today sells in the $3,600 range, making this well-preserved, fully serviced vintage example an attractive value. Includes an SKB hard shell travel case in excellent condition.
What makes this 1970 King 3BF special?
The nickel silver plating over yellow brass is rare for the model and provides a distinctive look while protecting the underlying brass. The lacquer finish helps preserve the plating and reduces maintenance.
