A straight Courtois bell section, model 360, 8" bell with a large-bore connector. Mates up perfectly with a Bach 42 slide with no tuning issues. Yellow brass, includes counterweight. In very good condition with a few very shallow bell dings. Lacquer is excellent. I like the more focused sound compared with the standard 8 1/2" 42 bell, but I am handicapped without the F-attachment. $375. + shipping from 08620 (NJ) including a big brown naugahide-covered Bach case in good shape.
