1945 King Liberty 2B trombone, s/n 275749. I acquired this trombone from an amateur musician who mostly played woodwind doubles. The trombone is in playing condition but will need an adjustment before it's optimal. The slide moves but feels slow or slightly encumbered. The tuning slide moves freely. It could be that it needs just a good clean and lubrication, but possibly some work will need to be done on the slide to make it perfect. No mouthpiece is included. There is a ding on the bell and the peg at the end of the slide is very slightly pushed in.
