I recently bought a well-used-but-playing 1960s Conn 20J to use at venues with a greater potential for horn damage. The more I play the 20J, the more I like it.
I only have a recording bell. I've looked around the internet a bit for an upright bell, but haven't found anything.
How hard is 20J upright bell to come by for sale?
Thanks.

20J and 24J were recording bell instruments. 21J and 25J were the same instruments with upright bells. Maybe a change in searches? Or try calling some of the major name repairers/restorers whose names you see here on TubeNet.

Kanstul makes a somewhat smaller replacement upright bell for the 2XJ tubas. I believe it's a bit pricey.
