Rare 1920s King Liberty Trumpet by H. N. White with reverse 2nd valve slide. As far as I can find, only silver-lacquered models from this time period had the reverse valve slide. Some very small dents here and there and an extremely small amount of lacquer wear. Plays great. Comes with a soft-shell case. No mouthpiece. 

I have never seen a trumpet even close to this age that is in such good shape.
