Rare Boosey & Co 4 valve Tenor Horn

This very rare Boosey & Co 4 valve Tenor Horn came into the Brass Workshop this week. It was made around 1920 and has been converted to low pitch. What makes it rare is the fourth valve which could have been added to help with tuning.  We didn’t know this model existed!

At some point is has been converted to low pitch and some of theBoosey 4v Tenon Horn slides have been replaced and it looks like the Bow has been replaced.
