| Steve,
When I was playing my Schilke S22 C trumpet I had the typical intonation problems that were the standard at the time for all horns. A fellow named Jack Holland invented a nifty litle device that enabled you to manipulate the tuning slide from a "zero" position in and out to raise and lower the pitch as you needed. Obviously, the tuning slide had to be relapped a bit to make it mobile before the device was put on. It was called the "pitch Finder" and was sold along with a record that demonstrated just intonation examples.
I outfitted my C trumpet and my little Alexander D with it and the orchestra rotaries which were Monkes at that time. It worked well but I'm glad I don't need it anymore. I don't know if someone else has taken over the patent as Jack died many years ago, unfortunately.
Jack was the solo cornetist with the Jack Daniels Silver Cornet Band and also played trumpet in the Puerto Rico Symphony for a time. He was a fine player and soloist.
