This is the bore size specified for the S43HDL-F.

Independent shopping perspective
The S43HDL-F is a Bb Jon Faddis model built around Schilke’s HD-series valve section for a heavier center. Its tunable yellow brass bell uses a medium throat and #3 taper, with more resonance and a more open feel emphasized in the upper register. The layout includes fixed first- and third-valve rings, a second-valve slide without nibs, and no water key on the main tuning slide. Heavy valve caps and an adjustable tuning-bell brace complete the design, and it comes with a custom single hard case.
