Another quick post. http://www.TrumpetMaster.com/vb/f140/auto-crat-cornet-48951.html#post454017. This is my cornet. Look at the bottom picture. Where the bell comes out of the valve body, there is a small dent before the tuning slide and after. I took something and rubbed the majority of the dent out. Of the part right out of the valve body. MAJOR difference.
