It’s not so much that they are collectors items as it is that they are special horns, part of the history of jazz as we know it. So, I wont go as far as to say that these are collectors items. That wasn’t the end of the flugelhorn, from what I hear, but they became more rare and hard to find after that. Then, in the early 70’s the factory burned down. The Couesnon flugelhorn was considered the go to flugelhorn for jazz players for many years. It’s in such wonderful condition that it should go to someone who is actually looking for a Couesnon. This is not a horn I want to go to someone who won’t appreciate it. The horn looks like it’s rarely been played. It’s got the original case, mouthpiece, lyre, etc. I have a Couesnon Flugelhorn for sale that is in very good shape compared to other flugelhorns from this time. I’ve been sitting on this for months and just haven’t had the time to tell everyone about it.
