We have on consignment a very nice vintage Bach 6 Stradivarius tenor trombone. With a .485" slide bore and a 7" bell, it's got the fiery, compact sound of the bands back in the day. This is a rare find for the vintage Bach collector. The model 6 was introduced in 1932.
Serial: 1734 circa 1940
Slide: gold brass .485", freshly tuned-up
Bell: 6 IV 7"
Finish: gold lacquer with tarnish at bell rim
Mouthpiece: Bach New York Jazz Model Small
Includes road-worn case and lyre
There is a loose piece of solder inside one of the braces. I have not settled on a solution yet. It plays fine and doesn't seem to rattle.
