Greetings. I am looking for some parts for a trombone, and if anyone has them, they would be greatly appreciated. I need a slide that works well. Prefereably dual bore (.547-.562) but a standard bass slide (.562) would work. I am looking or a bass trombone axial flow valve (Thayer valve), or perhaps some other sort of free-flow bass trombone valve. And finally, I need a bell, probably a Bach 50 (but only the 9.5 inch) in Gold brass, and as heavy as they make them. If anyone has any of these, or similar parts, please let me know.
