This is a nice semi-old horn from the days when Conn was making great instruments. It has an adjustable bell and comes with a Besson case. (I guess you can make people think you have a Besson until you take it out.) It is silver with gold inside the bell and has a worn finish. Current bid is $283.
ITEM SOLD FOR EITHER $283 OR $299
