You have found and are offerding on an outstanding example of the 22 Conn Trumpet. This was made in Elkhardt Indiana as all the good ones were! The case has what appears to be an Illinois University sticker still on the case. Cant you just see it out on the football field back in those days. Serial# is 195809...it comes with 2 mouth pieces, an Equa True#11 and a Conn small. Thequick slide has #6401 stamped on it, and a rotary valve. As with many old trumpets that have not been used, the slides will need freed. Feel free to ask questions....this is truly a great piece.
