\King 3B Silversonic with F-Attachment – Late 1960s, Closet Kept
Late 1960s King 3B Silversonic with F-attachment in outstanding, closet-kept condition — one of the finest examples of this iconic trombone we’ve had in recent years. Features all original parts with sterling silver bell, factory F-attachment, and .508 bore handslide.
Why do serious players and collectors consistently seek out vintage King Silversonics over modern brass instruments? It comes down to tone, craftsmanship, and that unmistakable feel — especially from the H.N. White era. The response, resonance, and balance on this horn are truly exceptional.
This one is super mint. The lacquer and plating are as good as it gets for an original late-1960s build — no redone work here. It's been carefully preserved and shows only the most minimal signs of handling. Plays fantastic, with a warm, colorful sound and excellent slide and rotor action. No service needed — it’s ready to go.
Includes:
Original King case in very mint condition
Rare King-branded canvas outer cover (also from the 1960s)
Original mouthpiece
King sales literature and paperwork
This horn is ideal for players seeking a flexible pro-level instrument with vintage character — perfect for jazz, lead, or commercial settings where clarity and projection matter. It’s also a smart choice for collectors who value originality and condition.
These factory F-attachment models from the '60s don’t surface often in this shape. If you've been waiting for a truly clean, all-original King 3B Silversonic, this is the one.
