I play BBb Tuba and a use a Marcinkiewicz  N3  and a H4  that both work well.
I also own a Yamaha 67C4 and a Miraphone Rose Model Orchestra.  I use the last 2 the least.  According to the Marcinkiewicz site says that the H4 is like the Conn Helleberg  and the N3 is like a Mirafone C3.   The best of both worlds.
