After 20 years of owning my Bach C trumpet it finally happened. I knocked it over on the 3 leg k and m stand and it fell over onto the middle slide valve denting the heck out of it. Major sad face. Is this a readily replacable part? If so my trumpet and my attitude will be much improved. Would love to be able to just order a replacement and have it fit. I could just live with it but it bugs the heck out of me.
