Hi!
The low and middle B natural fingerings are both the same...

Left hand: 1 and thumb
Right hand: Pinky

For the third octave, it's a little different...

Left hand: 1, 3, and thumb
Right hand: 2nd trill key

You need to blow forcefully to get the 3rd octave to speak. Don't overblow, but if the note isn't coming out, blow harder.

Note: "1" is the index finger. "3" is the ring finger.
