These are brand new, fully FAA approved knobs for all non-quadrant type Beechcraft Bonanza aircraft. The set includes are FAA paperwork, one black throttle, one blue prop, and one red mixture control knob, and all new screws for installation.

These are made of high-strength, space age polymer that will not crack or fade as your original knobs did. All knobs retain the vernier, screw type adjustability, and all knobs are knurled differently, to detect which knob you are selecting by touch. The throttle knob has a smooth feel, the mixture knob has two rows of bumps, and the prop knob has smooth ridges for easy identification by feel. Replace those old, cracked OEM knobs with these American made knobs. A nice cosmetic upgrade and easily identifiable knob set .
