Boosey & Co. Tenor Horn Class A light valve This is a tenor horn from Boosey & Co., the predecessor of Besson. The condition is good for its age. The soft parts have not been replaced, but the instrument has been cleaned. There are no major dents overall. It seems that only the 2nd piston button is different. There is a lot of solder on the tube coming out of the 3rd valve casing. The piston work is smooth. There is a crack in the slide, but it did not cause any problems during normal use. The blackening can be removed if you want, but I prefer the look as it is, so I used it as is, except for lightly polishing the bell engraving. The sound is a bit light, but the response is good, and I hardly noticed any pitch issues; I think it's a problem with my own skill. All parts can be removed and attached properly. I didn't see any places where the solder had come off. I am an amateur in terms of condition assessment, so I apologize if I have overlooked anything. Since it is used, returns are not accepted. A mouthpiece that appears to be original is included. I have confirmed that a trumpet mouthpiece can also be attached. The case is a Yamaha euphonium case that has been modified to fit this instrument.
