As this is a used instrument, it has dents and scratches here and there. But its rotary and tuning slides work without issue. I did not have any problem when I played it, but I suggest that you overhaul it to play in a better condition.
#1 Owing to the used products, they have partly dents and scratches,though, the rotary and in/out pipes can be operated without fail. Although I felt test playing wasn't so problem, it was given OH, would be better performance, I suppose.
