I stated the horn plays nicely, that this is a cosmetic issue. If this was not obvious to the eye, as well as to the touch, it would be a non-issue. No one is being smeared. This is simply an example of the trumpets from Getzen. This seam does have a notched "zipper" pattern that runs along the underside of the bell. And if Bach, and other companies that silver plate their horns have ridges/seams that are visible to the eye as well as the touch, then that is a simple fact of manufacturing. And this is an education for me as well. I have never observed an obvious seam in any silver plated trumpet that has been previously sampled.
