🟧 Archive & Reference Notice
This Olds O-25 has been sold and is now preserved here as a historical reference within our archive. It stands among the finest surviving examples of the company’s large-bore F-attachment design, built during an era when Olds set the standard for precision, balance, and tonal warmth.
The Olds O-25 Large Bore Tenor Trombone with F-attachment remains in super-mint condition, showing only minimal use — truly a closet queen preserved in its original form.
This model features an 8.5" gold brass bell, a lightweight nickel-silver handslide, and matching nickel-silver F-wrap and tuning slide. It plays with clarity, resonance, and an unmistakable Olds tonal core — warm, colorful, and vibrant throughout the range.
The rotor valve and handslide perform flawlessly, with exceptional compression and smooth travel. The horn accepts a large-shank tenor mouthpiece, and includes the original Olds mouthpiece in pristine condition.
Its original coffin-style case is also remarkably clean, completing an outstanding, all-original ensemble.
It remains a lasting example of true American craftsmanship, representing the dedication and skill that defined the Olds factory before its closure in the 1970s — a time when design, playability, and pride in workmanship were the hallmark of every horn produced.
