BMB Helleberg MP shank

[lowtones425]

Random question...

I recently acquired a Big Mouth Brass Helleberg, and it appears to be in Euro shank...

Were these MPs made in both Euro and American shanks, or just one?

I’ve found that the one I got works really nicely as a sousaphone piece...

You are correct that these are indeed Euro shank. The mouthpieces for those tubas only come in that shank size because those tubas are all using a Euro shank receiver.

I don't know about the mouthpieces, but not all their horns are Euro shank. My J-865 is American shank.
