I talked about this horn a few times on here as the best single valve bass trombone I have played - ever. A silver plated Thein Universal single valve bass trombone, screw bell and Hagmann valve.

It was off the market for some months, but now it is definitely for sale. Those don't come up often, so if you are looking for a great single valve bass, this is the ticket:
