Kruspe Compensating Descant Bb/F

I don't think I've ever encountered a horn like this before in my shop.  Its an unlacquered yellow brass compensating Bb/high F descant horn made by Kruspe! (The famed maker responsible for the horn which Conn copied and named the 8D!).  Though this Kruspe is a bit uncentered at times some TLC could make it a fabulous option for those high Haydn symphonies or Bach Cantatas.    No Case Included
