✦ Historical Overview
This Holton TR158 Large Bore Tenor Trombone, serial no. 529470, was produced in the late 1970s during the respected Elkhorn, Wisconsin era of Holton manufacturing. The TR158 represented Holton’s professional large-bore (.547") design, intended to compete directly with the Bach 42B and Conn 88H of its day. Built with an 8.5-inch rose-brass bell and a nickel-silver handslide, the model offered a balanced mix of warmth, projection, and durability suitable for both orchestral and solo performance settings.
This example received full shop service, including a chemical bath, rotor service, and slide adjustment. Although it has undergone light dent work, the instrument remains straight, responsive, and acoustically true to its original build. Slide alignment and compression are excellent, and the inner tubes show only minimal wear.
