This auction is for a vintage Conn 4 trumpet mouthpiece. It is quite used but still work well and seats nicely in a trumpet. There is no wobble assuming your leadpipe is not dented. As you can see in the photos, there are a couple of tool marks on the outer cup and on the shank of the mouthpiece. It plays very similarly to a modern Bach 7C mouthpiece. However, the inner rim is much sharper. What you see is what you get. No more, no less.NOTE! With the holiday season upon us shipping times tend to get longer.
