[Dixielandjazz] Tyree Glenn's 'Mood Indigo'

[Bob Smith]

I thoroughly enjoyed this YouTube video.

However it raised one question: Tyree uses two mutes. The loose one is a rubber sucker used for unblocking drains, etc. I use one of these myself. The other one that was fixed inside the bell didn't look familiar. I was wondering whether it could be a 'Pixie' mute?
Does anyone know?

Cheers
