Bach Stradivarius Trombone Model 12 with BAC carbon fiber slide

Bach Stradivarius Model 12 trombone with BAC carbon fiber slide. Instrument was purchased new around 2015 and later sent to Best American Craftsman in Kansas to convert slide to carbon fiber. BAC also converted the inner bell to a black matte lacquer. The trombone has been well used and there are a good number of scratches and pitting on the lacquer. On the outer bell there are marks near the emd of the bell. There are also several marks on the lacquer around the bell. On the handslide, there are plenty of marks and lacquer spots. As for dents, there are 2 major dents, as seen in the pictures, both on the bell, and both from me accidentally dropping my mouthpieceon the bell while assembling the instrument. The smaller dent has a small crease which concerned my that it might eventually need repair, but it didnt seem to effect the playability. There are no major dents on the slide, and the slide works great. (please see video). The inside of the bell with the black matte is very marked up and has blemishes, again see the pictures. Comes with a well-used Max trombone soft shell zipper caee. Condition of case is not great looking, but still protects horn well. No mouthpiece is included.
