This trombone is a Bach Stradivarius model 36Bb. It includes two mouth pieces: Bach 6.5al, Benge 12.c. Also comes with a straight mute and cup mute and original Bach case. The case has wear but is durable and has working clasps. The trombone is found to be in very good working condition, slide plays smoothly and freely with a minor stick at the top end. It does have typical wear of a used trombone that do not affect its sound (marks on finish, minor dents)
