What a beautiful horn! I found this horn sitting in the back room of a local repair shop. It had just been dropped off with a Lorenzo Sansone five-valve Bb (which I also purchased and hope that it will appear on this channel). I made a deal with the owner and purchased both horns. This Kruspe is in amazing shape for its age! I believe (though I don't have solid proof) that this horn is from the early 1900s. What a cool vintage horn! It cleaned up beautifully. This video gives a window into what I did to make this old horn sing again.
