Besson & Co were one of the most prolific brass instrument makers of the late 19th through the middle of the 20th century. Their instruments, especially older models, are known for sonorous tones and unique color capabilities. This horn's serial number dates around 1920. The valves have a little clank to them, but work smooth otherwise. The compensating system is located a little higher and at a different angle than most modern Euphonium designs, but the comfort is still there. The mouthpiece receiver requires a small shank mouthpiece. This instrument is excellent for players looking for a great bang for their buck towards a Euphonium with a compensating valve system. This is an ideal instrument for a growing musician.
