This is a customized Yamaha YTR-233 used trumpet. All slides move. The pistons also move. It's definitely rough-looking, but for those who like vintage, I think it has an irresistible appearance. As you can see from the pictures, the lacquer has been stripped, and there are dents and scratches. The bottom cap doesn't tighten well. If you like this kind of look, how about it? I think it's a pretty interesting trumpet. No price reduction is possible.
