The reason I put for parts are not working is because the third valve sticks. There are no obstructions in the horn, so it does play but once you depress that valve you got to grab it with your fingers and pull it back up. Up. So this is going to need to go to the shop before it is ready to play. It is also missing the little perloid topper on the third valve, the bell is dinged up pretty extensively. None of the slides are stuck. Comes with a Vincent Bach 6 and 1/2 AL mouthpiece which I believe is a small shank. The case shows wear and tear and has tape on it. The serial number is 1172 if that helps you date it. The case has a little placard that says made in Czechoslovakia, one of the latches will not close properly
