I have never been into playing flugelhorns, but recently have the opportunitty to get one in very good condition. The serial number on it 77XXX and I have no idea what they are worth or anything regarding any Couesnon instruments. I was going to sell it for a friend, but another Flugel player told me to buy it. Any ideas regarding quality and playability. Here is a link to the horn in question here: acarcido's Album: Couesnon Paris Flugelhorn Thanks in advance for your input.
