This is a beautiful Conn 17A Coprion bell cornet that dates to 1956.
 
From Conn:

Completely New, these Conn Directors offer new and greater heights of performance for the aspiring young musician. Even the untrained embouchure can easily play each note right on the button due to the remarkably centered response. Every minute detail has been specifically designed and created with the student in mind so that he may quickly progress to the best of his ability. The new Conn Directors are acoustically, mechanically, and musically superior... without doubt the finest value in this price range!

Special features of the new Directors: "Anti-Bounce", positive, quiet valves. Bell thickness graduated for finest tone. Newly calibrated bore for easier high register. Brilliant, longer lasting "Lustre-Conn" finish.
 
 
Condition: Very good with some lacquer wear thoughout. Valves and slides are buttery smooth.
