I've been playing the trumpet for around 7 years, all in high school though. I've been playing on a very old Yamaha, and wanted an upgrade. I found a Bach Mercedes, but it needs alot of work. The bell has a crinkle in it, many parts need to be saudered, and the instruments silver plating is no longer silver. Around how much would it cost to repair this? If needed, I could probably post pictures of the instrument tomorrow.
