Excellent horn and price. These were often used as Intermediate horns by high schools in the 60s and early 70s. The only problem is that are more difficult to march with than American style. There is not a false tube full handle behind the valves, just a thumb ring. When marching with these, the thumb gets tired. I marched for 2 years in the Cal Band with a bell front version of one of these.
