📸 Photography From Our Early Archive
These images were taken during the earlier years of The Brass Exchange, before our current Nikon Z5 + studio lighting workflow. We keep them here as part of our historical archive—both as documentation and as a visual record of how our brass photography has evolved.
Conn 6H Vintage Elkhart Era, 1967 Make, SN K89799.
This is a true classic from Conn’s Elkhart period, built in 1967 with all original parts, lacquer, and case. The 6H model has long been regarded as a professional-level jazz trombone, famously played by Frank Rosolino and admired for its tone, balance, and agility.
We performed a full shop service here at The Brass Exchange including chemical bath and precision slide alignment. The horn plays beautifully with a responsive, even feel throughout all registers. The inner slide tubes are clean, straight, and free of plating loss.
There is some lacquer loss on the bell and outer slide, consistent with age, but nothing that affects performance. A notable area of abrasion appears around 9 o'clock on the bell stem where it meets the flare (as viewed from the player’s perspective), but it is cosmetic only. Importantly, the horn is completely dent-free, structurally straight, and has never suffered major damage.
Specs include an 8" yellow brass bell with unsoldered rim, and a gold brass .500 bore handslide—ideal for lead and solo work, but versatile enough for section playing. The 6H offers a warm, flexible sound with just the right edge for jazz.
Why is the Conn 6H so highly regarded among jazz trombonists?
The Conn 6H combines a light, fast handslide with a resonant yellow brass bell, producing a vibrant tone that cuts without being harsh. It’s a model known for exceptional response, which is why many top players—from Rosolino to modern pros—continue to seek them out.
