Here are some pictures of the trumpet I asked you about lase week. I was wrong on where the valve was.

The rotary valve in your Besson trumpet is for changing the key of the horn to A without having to change the position of the tuning slide. You will also find markings on the valve slides because you must also pull the valve slides out for the entire horn to be in tune playing in A.

At the time your horn was manufactured, there were still some older arrangements that used a trumpet pitched in A, mostly for an easier key signature. Those parts are virtually non-existent today, so there is no more call for horns to be able to easily be pitched in A.

It is usually best to have a repair technician pack that valve with a thick grease so it doesn't leak and doesn't seize.

I can answer your questions about Buescher trumpets and cornets. I have been playing Buescher for 35 years and collecting for 7.


I first started playing my grandfather's Buescher 400 trumpet in 1975. Since then I have done a lot of research, including original catalogs and advertisements that I own, correspondence with other Buescher owners, and obtaining my own Buescher collection, including six trumpets and three cornets.

I am a technical writer with 15 years experience. I have also been playing trumpet since 1975 and collecting Buescher for the past 7 years.
