I purchased this trumpet from Dan Truitt, a dear friend and colleague of mine, and the head of instrument repair at Sacramento State University, former technician at Schilke, and apprentice under Wayne Tanabe at the Brass Bow in Chicago. I performed with Dan as a youth in the Phantom Regiment Drum & Buble Corps in the early 1990's, so we go way back, old school all the way! Dan stated to me that he had a trumpet he was working on and simply had to time to complete it. He then let me know that it was a vintage Schilke X3L from the 1960's.......sold! He sent me most of the parts and hardware, and I after having it sit behind other work I was doing for 5 months, I got to work!
