I searched the site and didn't see a ton of information related to Couesnon baritones or euphoniums, but wanted to get some feedback on the following. I saw a 3 valve Couesnon Baritone Horn (although I think it might actually be an euphonium) listed on Craigs list. Some fairly good pictures of it and selling relatively inexpensively. ~$200.

I told a friend from church and he checked it out and didn't seem to think it sounded that great in the lower register (He's a trombone player) I've considered checking it out either to play for myself or to fix up and re-sell, just wondering what it might be worth and what to look for in an Euphonium and if anyone can tell me more about this which when zooming the picture appears to be a Lafayette Couesnon Baritone horn.
