From Brass Ark I recently bought this wonderful Bach 36GH bell with dual bore .525 (36) and .547 (42) slide. I bought it for the slide (already have a couple fave bells) so this bell is available. This is an Elkhart heavy gauge 8" gold brass bell with connector for .547 slide. Noah was right - it is a great bell, in excellent condition, just not my preference. $1000 with original case shipped CONUS. Can throw in a generic .547 slide. Email for pictures, additional details.
