Plane with no stall warning device?

The Cessna 501 and 551 (better known as the Citation I SP and II SP) meet
part 25 requirements, but are placed under part 23 for single pilot
operations. They have no stall warning devices. There is a very
significant prestall buffet.

My Tri-Pacer had none.

Because I fly, I envy no one.

Researching a question from a club member, I read in the FAR's:

§**23.207 *Stall warning.
[...]
(b) The stall warning may be furnished either through the inherent
aerodynamic qualities of the airplane or by a device that will give
clearly distinguishable indications under expected conditions of flight.

Every plane I've ever flown has a mechanical stall warning device (some
visual, some aural), but apparantly it's possible to certify a plane
without one. Does anybody know of any real life examples of planes
certified without stall warning devices?

Whole bunches of early machines don't have them including (but not limited
to

Piper Cub series
Taylorcraft BC-12D
Pitts Special
P-51 Mustang
Corsair
Spitfire

The Falco had an aerodynamic rather than mechanical. There's a false
leading edge on about 6 inches of the wing which causes turbulent air over
that section and makes a buffeting on the wing to give the indication of an
impending stall.

I personally haven't flown an airplane with a stall warning in about 250
hours (last 5 years or so) and, quite frankly, would rather do without the
racket.

GLIDERS

Gliders use no mechanical nor electric stall warning devices.

They use the glider.

By feeling the air, feeling control response, remaining cognizant of
roll pitch and yaw attitudes relative to airpeed, watching airspeed,
feeling g forces; watching horizon, watching changing clouds, birds,
smoke, sun angle, wind shadow on water, other aircraft, ground,
terrain features and all outside glider;
keeping glider in coordinated flight by centering yaw string on
front center of canopy, listening, feeling, dancing on clouds, to
keep flying they keep flying, generally without stall.

It is blessed to not have a stall horn aboard.

Gliders often have stick w/elevator trim, ailerons, rudder operated by
adjustable pedals, spoilers or dive brakes, many have manually
operated flaps with positive and negative position settings for climb
cruise and fast running, retractable landing gear, disposable water
ballast, 12 vdc battery elec systems, flight computers linked to gps
maps and sensitive rate of climb indicators w/adjustable sound.
Gliders are usually configured as inline two seaters for training, or
supine single seaters with long plexi canopy for personal use
including glider racing or cross country flying. Modern high
performance gliders are made of glass composite fiber materials
(reinforced plastics).

Thereupon one finds a plane without a stall horn.
