Holton TR156 1970s Large Bore Tenor Trombone with Detachable Bell Flare – Archive
The Holton TR156 represents a unique chapter in American brass instrument innovation. This example, from the 1970s, features an original factory detachable bell flare — sometimes referred to as a "screw bell," a concept long used in the French horn world.
This design allowed players to travel more easily with large instruments, as the bell flare can be separated and packed compactly — a forward-thinking feature that was rare on trombones of this era.
The TR156 is also known as the Jaz Friedman model, and it offers a dual bore .547/.562 handslide paired with a 9" rose brass bell, resulting in a warm, broad sound with excellent projection and tonal depth.
This horn is in excellent condition and plays fantastic, with no major signs of wear or damage. It is a single-owner instrument, further adding to its historical and collector appeal.
Holton has a rich history dating back to the 1890s, exemplifying true American craftsmanship and a dedication to advancing brass instrument design. The TR156 showcases this spirit of innovation — blending tradition with practical, player-focused solutions.
Includes the original case, providing secure protection for this special piece.
Why would a trombone player consider an instrument with a detachable bell flare (screw bell)?
Detachable bell flares — also known as "screw bells" — have long been popular among French horn players for easier travel and compact storage. Over the past decade, this concept has become increasingly common among professional trombonists and college-level players, who appreciate the added convenience and flexibility.
A detachable bell design allows the instrument to fit into smaller cases, making it much easier to travel with — especially on airlines, where it can fit into overhead compartments rather than needing to be checked.
The Brass Exchange offers an exclusive line of modern screw bell cases made in Italy, designed specifically for these needs. Learn more about these premium options here: Tenor Trombone Screw Bell Case – DR Artist Model.
