We need a lot more information and perhaps a picture or two. Since you don't have 3 posts, you can't upload pictures yet. But if you can host them on another site like DropBox you can reference their URL's and we can look at them.

First, is this a straight trombone or does it have a valve?

What does the bell engraving say?

From what you posted we really can't tell you anything.

Bell engraving and/or the stamped numbers at the top of the slide by the tenon that attaches to the bell.

Whatever it is, it was probably made in 1977
