I purchased this item used, but only used it a few times before storing it at home. I don't know much about the year or brand. The sound works fine. Sometimes the pistons don't slide smoothly, but I've cleaned them and they work without issue. The pipes can also be removed without any problems. The case has some stains. There are no cracks. The accessories were mostly unused and are in the same condition as when I purchased them from the previous owner. There are no major scratches or dents, but there are some small scratches. Also, the mouthpiece is discolored, but it can be cleaned. The main body and mouthpiece have been disinfected with alcohol. Would this be suitable for practice?
