Heckel (110) / Fox 42

No Bb-key for R-3f

Use:
R-3f cannot slip off of G-key unintentionally

Note:
Slurs between low-F# and Bb above must be accomplished with the R-t, risking disruption in the legato, or must be accomplished with the F#-key for R-4f which is inferior in intonation to F#-key R-t on most makes of bassoon.
