The traditional German and Czech instruments do not have a removable receiver like the American/Japanese instruments. For this reason, German and Czech instruments normally have a mouthpiece where the metal is thin at the end of the shank, or a bevel is cut on the end to reduce turbulence. When the mouthpipe was being made, a nickel-silver tube was placed on the receiver end, and then a flaring tool was used to flare the mouthpipe inside the "receiver". It is normally soldered, just to make sure it stays tight.
If you are having response problems associated with mouthpiece fit, the easiest remedy is to have the shank end of your mouthpiece back-cut, ie., have a bevel cut in it to reduce any unwanted turbulence. This will "open-up" a horn more than you would expect.
