I received this euphonium many years ago from an old music teacher of mine. He was an elderly gentleman and had traveled much of his life. I am having trouble identifying the brand, nothing is stamped on the horn itself or the case. The only numbers I can find are on the center valve but there are only 2 numbers- 62.
