Overview
This King 2B Silversonic “Liberty” tenor trombone is an exceptional Cleveland-era professional instrument with sterling silver bell and original gold-washed interior. The engraving clearly reads King Musical Instruments, placing the instrument in the classic Cleveland production period before the Eastlake transition.
Sterling-bell King 2B Silversonic trombones are rarely produced in modern Conn-Selmer production, making original Cleveland-era examples especially desirable to players and collectors.
The bell lacquer has been professionally removed from the sterling-silver portion and polished — a common preference among professional Silversonic players who want a lighter feel and more immediate response. The gold wash inside the bell remains original and intact, slightly faded but clean with no defects.
This instrument came from a trusted professional player and has received full shop preparation here at The Brass Exchange..
If you’re a professional player searching for a truly exceptional King 2B Silversonic based on playability, or an advancing jazz player looking for a dependable lead horn with real Cleveland character, this instrument deserves serious consideration.
Player Perspective
This is one of the best-playing King 2B slides we have seen at TBE.
Our standard preparation included:
• Chemical bath and full flush
• Inspection for dents or prior damage
• Water key pad replacement
• Slide prep with inner outer-tube polishing to remove oxidation buildup
• Alignment check and play-test
No repairs were required, and no previous damage was found.
Oxidation buildup is one of the most common causes of sluggish slide feel even when tubes are straight. After proper prep this slide feels fast, responsive, and effortless — exactly what a professional small-bore King should do.
The previous owner was a high-level U.S. Air Force trombonist who likely had this instrument professionally set up and used it as a working horn. It plays with the classic King 2B clarity and immediacy that made these horns famous in studio, jazz, and commercial playing.
Included is a Walt Johnson shaped touring case, widely regarded as one of the most protective fiberglass flight cases ever made.
How We Estimate the Era of This Instrument
Dating King trombones from this period requires more than just serial numbers.
For this instrument we rely on:
• Engraving style – “King Musical Instruments” Cleveland format
• Construction details – Liberty-style bell, sterling Silversonic build
• Materials – gold-washed sterling bell, classic small-bore geometry
• Shop experience – comparison with hundreds of Cleveland-era Kings
These features place the instrument firmly in the late Cleveland era (1950s–early 1960s).
This method is standard practice among collectors because King production records were not always consistent.
About the Number Stamped on This Instrument
Many King trombones from this period were stamped with assembly or batch numbers, not full instrument serial numbers.
King serial number charts typically apply only to specific professional models and certain factory periods. Student instruments and replacement slides often used different numbering systems.
Because of this, a four-digit number on a slide is usually an internal assembly number rather than a serial number. This does not affect authenticity or value, but it can make dating instruments confusing for collectors.
When customers contact us with similar questions, we look at engraving, materials, and construction details — not just numbers — to determine era and authenticity.
About the Walt Johnson Touring Case
Walt Johnson fiberglass cases were legendary among touring professionals from the late 1970s through early 2000s. Hand-laid fiberglass shells and heavy-duty hardware made them extremely protective — often called “bullet-proof” cases in the professional community.
These cases were produced in small numbers in California workshops and sold primarily through specialty dealers and word-of-mouth networks. Many are still in use decades later because of their durability.
Including one with this instrument adds real long-term value for a working musician.

Questions Trombone Players Often Ask
Q: Does removing lacquer from a Silversonic bell change the sound?
Many professional players feel that a raw sterling-silver bell responds more quickly and feels lighter to play than a lacquered version. This example was polished with lacquer removed only from the sterling portion, and it plays evenly with excellent clarity.
Q: Are assembly numbers normal on King slides?
Yes. Many Cleveland-era Kings were stamped with internal assembly or batch numbers rather than full instrument serial numbers. King serial charts apply mainly to certain professional models and periods, so we rely on engraving style, construction details, and shop experience when estimating era.
Q: Is this suitable for professional jazz or studio playing?
Absolutely. The King 2B Silversonic is one of the classic small-bore professional trombones, prized for clarity, articulation, and immediacy in studio, big band, and commercial settings.
Q: Are sterling-silver King 2B trombones still made today?
Modern King Legend-Series 2B models have occasionally been offered with sterling-silver bells in limited runs, but true Cleveland-era Silversonic examples like this are far less common and remain especially desirable to players and collectors.
Q: Why don’t many professionals prefer epoxy-lacquer restorations?
A baked epoxy lacquer can look beautiful and protect the metal, but many players feel it adds weight and changes the response of sterling-silver bells. For that reason, experienced players often prefer original lacquer or raw polished silver when possible.
