This is a 1931 BBb Martin Mammoth Handcraft. And yes, the bell is original. I'm curious about the leadpipe though. I don't think it's original. Did Martin only make the receivers with bits set up for recording bell tubas? Does anyone have a similar Martin Mammoth with one piece, upright bell that they can post pics of?
As you can imagine, it's an awesome instrument!
Thanks for the input,
Frank
