Thank you for viewing! This is a Theodor Heckel alto trombone, the pinnacle of German trombone craftsmanship. It's a very rare instrument with a large bell (200mm). The inner slide is not chrome-plated, but it slides very smoothly with YAMAHA slide oil. The intonation within the positions is excellent, and the high D-flat plays perfectly. I'm selling it because I'm focusing on bass trombone and don't have time to play the alto. I'm not in a rush to sell, so I've set a reasonable price. Egger makes a Heckel alto replica. The replica costs $6400, but they sell quickly and are difficult to obtain. https://brassark.com/maker_horns/egger-alto-trombone-in-eb-after-heckel/ Heckel altos are rarely available on the used market, and this large-bell specification, which makes a strong presence in orchestras, is a very valuable and rare instrument.
