I'm looking for an upright bell for one of these horns;
Reynolds Contempora tuba recording bell 44046
Olds tuba recording bell 639167
The current recording bells are interchangeable and I'm not picky about branding.

Any advice for finding a bell for one of these? What other makes and models might work?
Any suggestions for modifying or....making one (I do know that that sounds ridiculous but I might as well ask)
It seems that many people are looking for upright bells for various horns in the WTB/Seeking section. I wonder if in 25 years there will be as many folks looking for recording bells.
