Does anyone know if a 1920s Martin sousaphone bell will fit a 1959 Martin Mammoth, to be used as a forward facing bell? It looks like the sousaphone bell has the same small diameter on the tuba end, and 24” on the business end. But would it have the correct angle for a forward facing bell? Thanks B ...

Can someone please post a link to this one? I can’t seem to find it on Facebook Marketplace. Thanks.

Anyone ever heard of one of these before?

Interesting Sousaphone for sale. Anyone know anything about these "Williams"?
