This is a generic wood shell cornet case for Bb and Eb cornets. This case fits the following cornets: Bach 184 Bb cornet, Getzen 800 Bb cornet, Schilke XA1 Bb cornet and Shepherd's crook Eb cornets.
I have a Getzen Eterna cornet, it is kind of weird shape, so it wouldn't fit in most other cases. It fit in this one no problem. I like this style of case. It also has a compartment in front and under the cornet. My only complaint is it doesn't have a mouthpiece holder. I keep my mouthpiece either on the receiver or in a pouch underneath.
I've been having a hard time finding a case for my Getzen Eterna cornet because they have a strange configuration. I knew immediately it wouldn't fit into most cases I looked at, but then I found this one. It fits perfectly! And the case is only $50. I would give it 5 stars but it doesn't have a mouthpiece holder, but I will buy a mouthpiece pouch and store it in the compartment under the cornet.
