King 3B bell on Selmer Bolero slide?

[Basie1955]

Hey all,

Wondering if anyone has tried a 3B bell on a Bolero
slide? I currently don’t have a 3B bell to test out.
I’ve read that the Bolero was roughly based on the 3B
but curious how the tennon and threading would
match up.

Big thanks

They are not compatible without modification. Bolero has the nut on the bell section, King has the nut on the slide.

Thanks for the info!
