I was just recently given a 1927 26k Eb Sousaphone.
It was terribly tarnished but other than that it looks to be in playable condition.
It is missing the neck, bits and a mouthpiece.
I was looking at earlier posts regarding the 26K and found one that said any neck and bits from numerous models (including BBb sousaphones) are the "correct" parts for this horn.
Can anyone confirm that? I am a band director and hope to get it in playing codition for one of my students to use.
