First post to the forum...
I just wanted to let people know that I'll be visiting the Buffet factory in Germany next week (where they produce all the Besson Euphoniums).
This is the address: Gewerbepark 52, 08258 Markneukirchen, right next to the Czech border.
I'll write up my experiences once I'm back, but if there is anything in particular anyone would like to find out add an entry to this thread.
