This is a mint condition Getzen 725F Eterna II tenor trombone. It's made in Elkhorn Wisconsin, and this design was formerly sold as part of the Canadian Brass trombone series back in the day. Compare this to a Conn 88H, but with its small shank receiver and smaller upper slide tube, the Getzen is a bit snappier. Construction and finish work is top notch.
This one is in mint condition, owned by a local professional who's reducing his trombone arsenal. Not a mark on it. Slide is maintained by John Sandhagen.
