This is a CONN model 50H trombone with F attachment . My daughter has used it for marching band and practice at home for 3 years , she has had no problems with it at all . I am selling it because she no longer needs it . It is ready to play and works great although it does have some scratches and dents . I took pictures of the very obvious dents . This would make a very good 2nd trombone for practice at home or for marching band . Case is the original CONN case and is in good condition for it's age , all latches on the case work .Mouthpiece not included .

Here is a link to some more info on this model , including the bore size bell size etc .  I will ship it Fedex 2 day air for 12.00 , you will get it quick .
