Alto Horn Courtois AC180 Tenor Horn Courtois

I used this for about 10 years in a brass band.
It worked hard as my main instrument, so as you can see, the lacquer is quite damaged.
It has a very good resonance and I like its tone.
Whether it was my playing style or the instrument itself, it was slightly high-pitched, so I always pulled out the main slide about 3 cm.
There is a dent on the edge of the bell. (See 6th image)
It's hard to part with, but I'm considering selling it to downsize my equipment as I've replaced my main instrument.
