Conn 6H Trombone Bell – Serial #715610 – Elkhart Era, 1957.
This is an original vintage Conn 6H from the golden era of Conn production in Elkhart, Indiana. The 6H was famously played by jazz legend Frank Rosolino and the entire trombone section of the Stan Kenton Orchestra. It remains one of the most iconic .500 bore small bore jazz horns of the 20th century.
This listing includes the bell section only plus the original slide, which is currently unplayable and in need of a full rebuild. The bell itself has undergone full shop service here, including chemical cleaning, dent removal, and polishing. It’s a classic 8" yellow brass bell with an unsoldered rim that gives the 6H its open, flexible sound. Structurally solid, no major trauma—just aged lacquer and a bit of surface wear consistent with its era.
The original outer slide (gold brass) has multiple dings, and the inner tubes are not usable in current condition due to damage and plating wear. In our opinion, this slide is only salvageable with a full rebuild or total replacement.
That said, the bell plays beautifully with a working 6H slide. I personally tested it using my own 6H setup, and it plays a little darker than my 1960s model. There's something special about these late 1950s bells—they often have a slightly thicker tone with great core and warmth. If you’re already a Conn player, this could be an ideal secondary bell to rotate into your setup.
Conn used a standardized .500 bore slide across several models, including the 6H, 48H, 5H, and 100H. That means this bell is compatible with any .500 bore Conn slide, vintage or modern.
Includes Case as pictured. Although the slide will require repair- rebuild, the bell section is fully serviced and a solid player when paired with a compatible .500 bore slide. This is a rare opportunity to own a 1957 Elkhart-era 6H bell at a reduced price—ideal for Conn fans, tinkerers, or anyone seeking a project horn with pedigree.
What makes this Conn 6H bell from 1957 special?
It’s from the coveted Elkhart production era, known for tonal richness, warm response, and classic jazz pedigree. The unsoldered rim and original alloy give it a sound profile that’s slightly darker than later Conn 6H models.
Is the slide usable as-is?
No. The slide requires a full rebuild, including replacing inner tubes and addressing numerous dings in the outers. This listing is best suited for someone with access to a good technician or another compatible .500 bore Conn slide.
Can I use a different Conn slide with this bell?
Yes. Most Conn .500 bore slides (6H, 48H, 100H, 5H) are mechanically compatible. Many players mix and match components, especially when sourcing vintage parts.
Is this a good fit for a student or beginner?
Not in its current condition. This is better suited for a Conn collector, project restorer, or an experienced player who already owns a .500 bore slide and is looking for a vintage Elkhart bell.
This Elkhart 6H was priced accordingly due to the slide damage. A great option for players seeking a legendary Conn bell or collectors looking for a project horn with history.
