Conn Director (1965) Bb Cornet with Coprion Bell.
Condition of the lacquer is fair. Technical condition is very good.
Information by Conn about their Coprion Bell (derived from The Conn Loyalist):
The process necessary for producing the Coprion bell was developed by Conn in 1938. It consists of electrolytically depositing COPper IONns (hence the name Coprion) onto a stainless steel precision form accurate to millionths of an inch (so Conn said in its 1959 catalog), creating a seamless bell. Coprion isn't the same as a "rose brass" or "red brass" bell; these are brass bells with a higher copper content. Coprion is 100% pure copper.
What about the sound?
It is said that on an instrument with a Coprion bell "you can't overblow or 'crack' a note." Also, according to Conn, "Coprion has a special characteristic which permits great dynamic range without change in tone color."
It is generally accepted that high(er) copper content bells make the sound "darker" and have better projection.
