I just received from my uncle the Cavalier trumpet he played probably in the 40's and I played in the 60's. When I graduated from high school I gave it back to him and his son played it. On the second valve are the number 67919. It is silver in color but not shiny except on the bell where it is fancy with with a decortive cavalier and Elkhart, Ind. USA. The inside of the bell has a goldtone. Can anyone tell me anything about this horn?
