Genuine Bach trumpet, round crook tuning slide for 180ML, silver-plated finish. This is a used item, so there are some scratches and plating wear. There are no dents. It has been disassembled and repaired once, so it is priced lower, but I think it has been handled cleanly. (Balance adjustment of the pillars, not dent repair) This is a special order-only part, and it seems that a new one would cost over 50,000 yen now. Price negotiations are welcome within a reasonable range. The 180MLSP is a classic instrument and is wonderful, but I think you may sometimes feel it's a bit too tight. Changing to a genuine round crook will change the balance. However, it doesn't feel like the air just escapes, and it has a moderate resistance, so I liked using it. I am selling this because I no longer need it, as I have sold the Bach instrument body. Please judge the details from the photos, as it has been used for a while. Adjustment may be necessary depending on the instrument it is used with. I can basically ship within 1-2 days, but I am occasionally unavailable for about a week. In that case, I will temporarily suspend the listing, but if it's a sudden timing, I may need some time.
