I purchased this online and installed it on my instrument after opening the package, but it didn't fit, so I'm putting it up for sale. ⚠️Caution⚠️ When fitted to a YHR-87D, the distance between the thumb lever and the tubing was too close, and it rubbed against the leather cover, preventing smooth movement. It might fit if you have a shorter thumb lever. -------------------- Brown leather protector for French horn, protects your instrument well. - Brand: Galax - Model: French Horn Protector DX B Type - Color: Brown - Material: Leather - Purpose: Instrument protection Thank you for looking.
