Kuhnl Hoyer K&H 512 Bart Van Lier Model, Small Bore Kuhnl & Hoyer Tenor Trombone German Made Thank you for viewing. I am selling this trombone because I no longer have many opportunities to play a small bore instrument. I purchased it used in 2022 and used it as my main instrument for about two years. I consistently performed daily maintenance, such as greasing and swabbing. There are some scratches on the bell. There is also some wear on the areas that are typically touched by hands during use. The slide and main tuning slide move very well. There is a large dent on the tip of the outer slide, but it did not affect playability. The stand is not included, as it was used for photography purposes. The original soft case is included. If you would like additional detailed photos, please comment. Thank you.
