Waltham Model XA-Type 37This Clock had luminous hands, dial indexes, and Arabic numerals. A small second sub-dial was located just below the 12 o’clock index. The XA Model was able to perform accurately under extremely difficult environmental conditions such as vibrations, and exposure to sudden and extreme barometric and temperature fluctuations commonly encountered in aircrafts. Built in the twenties, it was the most reliable clock of its time.  Lindberg chose it for the historical flight,  because he preferred accuracy over reliability.
Oil TemperatureIndicates the Engine Oil Temperature.
Control Stick
Fuel MixtureSets the amount of fuel added to the intake airflow.  At higher altitudes, the air pressure (and therefore the oxygen level) declines so the fuel volume must also be reduced to give the correct Air/Fuel Mixture.  This process is known as "Leaning".
Turn On Gravity IndicatorIndicates the rate of turn, or the rate of change in the aircraft's heading.
Officially Called: Ryan NYP (for New York to Paris) Modified: Ryan – M2 by Ryan Airlines Registration #: N-X-211
Oil Pressure GaugeIndicates the supply pressure of the engine lubricant.
TachymeterThe airplane tachometer shows how fast the crank or propeller shaft of the engine is revolving. As a rule it indicates the revolutions per minute, or R.P.M. of the shaft.
Wicker ChairA Wicker Chair by any other name is still, a Wicker Chair. The cabin was so cramped Lindbergh could barely stretch his legs. To save weight, he bought a Wicker Chair instead of a regular pilot's seat. His meals were sandwiches from a paper bag and a canteen of water.
Cockpit Information (Click Green Background To  Close) In 1919 Raymond Orteig, a New York City hotel owner, attended a dinner in New York City, organized by the Aero Club of America, honoring the American flying ace Eddie Rickenbacker. Influenced by Rickenbacher's speech about the strained friendship and relationship between France and American, Orteig offered a prize of $25,000 to the first person to fly non-stop, between New York and Paris, in either direction. Charles Lindberg, an unknown pilot from the Postal Service, convinced a group of businessmen from St Louis, Missouri, to try to win that reward. With a budget of only $15,000 at his disposal, he contracted the Ryan Airlines Corporation out of San Diego to build his plane. They offered to do the job for $10,580. Mechanically gifted since childhood, Lindbergh personally made sure that the plane was constructed well. Loosely based on the company's 1926 Ryan M-2 Mail Plane, it took two months to prepare it. The single engine monoplane was powered by a 223-horsepower (166 kW), air-cooled, 9-cylinder Wright J-5C "Whirlwind" Radial Engine. It had a 46-foot wingspan, 10 feet longer than the M-1, to accommodate the heavy load of fuel that it would need to complete the flight. Officially known as the Ryan NYP, it was re-named "The Spirit of St. Louis" in honor of Lindbergh's supporters from The St. Louis Raquette Club. Lindbergh included no luxuries. The plane itself was designed with no forward looking windows. Two side windows, a small skylight and a Periscope to see forward were the only way to see out during normal flight. The cramped cockpit was 36" wide by 32" long by 51" high (94 cm x 81 cm x 130 cm). The cockpit was so small, Lindbergh could not stretch his legs. Only those things that were absolutely necessary were taken along. There were no parachute, navigation lights, gas gauges, or radio on board. To save even more weight, he bought a Wicker Chair instead of a regular pilot's seat. He even made his own lightweight flying boots. He tore the extra pages out of his notebook and cut the edges off his charts and maps!  The Wicker chair was intentionally made to be uncomfortable to help in keeping him awake during the long flight. His meals were sandwiches from a paper bag and a canteen of water. On the tenth of May 1927, Lindberg flew from San Diego to New York establishing a new record for a transcontinental flight. On the twentieth of May, he took off in a solitary flight from Roosevelt Field, Long Island and landed in Le Bourget Field in Paris, France 33 hours and a half later. He had made it to Europe at 10:24 p.m. on May 21, 1927, and was stunned to find 150,000 people waiting to celebrate his remarkable accomplishment.
Splitdorf Magneto SwitchThe Ignition Switch has the following positions: Off: Both magneto p-leads are connected to electrical ground. This disables both magnetos, no spark is produced.  Right: The left magneto p-lead is grounded, and the right is open. This disables the left magneto and enables the right magneto only.  Left: The right magneto p-lead is grounded, and the left is open. This disables the right magneto and enables the left magneto only.  Both: This is the normal operating configuration, both p-leads are open, enabling both magnetos.  Start: The pinion gear on the starter motor is engaged with the flywheel and the starter motor runs to turn the engine over. In most cases, only the left magneto is active (the right p-lead is grounded) due to timing differences between the magnetos at low RPMs.
Fuel Pressure GaugeIndicates the supply Pressure of Fuel to the carburetor.

Pioneer Earth Inductor Compass System
Pioneer Earth Inductor Compass Directional Charles Lindbergh relied on this type of 3 piece compass on his New York to Paris flight to maintain course until it malfunctioned.  It's primary attraction featured a controller that could dial in a heading that could be followed with the Left / Right Indicator. (Visible On The Instrument Panel) • Outer Ring: Current Heading•  Inner Ring: Desired Heading This made it far easier to hold a heading over long periods, particularly when fatigued.  It used a Wind-Driven Generator to create an induction field. The Anemometer or Windmeter that produced this electrical output was located above the fuselage just behind the wing. This 3 piece system fell out of favor by the mid-1930s.
Magnetic Compass & Mirror This was the Magnetic Compass that was directly above him. It was positioned in such a way to be away from as much metal as possible.  Problem was, It Was Right Over His Head, so he couldn't read it directly.  So the Bendix Company which made the compass created a type of compass that actually had the numbers on it reversed, so he could get the compass readings by looking into the Mirror, below it. 
Stores Jettison(Click Green Background To  Close) Provides the capability of phase jettison of all external stores or symmetrical jettison of fuel tanks. EMER JETT ALL:  Applies 28 volts from essential dc bus to all stores stations when the helicopter weight is off the wheels. JETT: Applies 28 volts from primary dc bus through the rotary selector switch to the selected stores station if the weight is off the wheels and the selector switch is not OFF. Rotary Selector Switch OFF: Prevents jettison signal from going to any stores station. ALL: Directs primary jettison signal to all stores stations. Outboard stores           will jettison and 1 second later inboard stores will jettison.• INBD     ◦ L: Directs jettison signal to inboard left station.     ◦ R: Directs jettison signal to inboard right station.     ◦ Both: Directs jettison signal to inboard left and right stores                             stations.• OUTBD      ◦ L: Directs jettison signal to outboard left station.     ◦ R: Directs jettison signal to outboard right station.     ◦ Both: Directs jettison signal to outboard left and right stores                            stations.
Main Gas Tank The Ryan NYP had a total fuel capacity of 450 U.S. gallons of gasoline, which is what Lindberg felt that he needed in order to have the range to make a non-stop flight across the Atlantic Ocean.  The fuel was held in 5 Fuel Tanks. A Main Tank with 209 gallons, the Forward Tank holding 88 gallons, and three Wing Tanks with a combined total of 153 gallons. At Lindbergh's request, the large Main and Forward Fuel Tanks were placed in front of the pilot, with the Oil Tank acting as a firewall. He felt that this improved the plane's Center of Gravity and reduced the likelihood of the pilot being crushed between the Main Tank and the Engine in case of a accident.  I don't know why he was worried about being crushed, the plane was quite literally, a FLYING GAS TANK.
Pioneer Earth Induction Compass Left / Right Turn Indicator Charles Lindbergh relied on this type of 3 piece compass on his New York to Paris flight to maintain course, until it malfunctioned.  It's primary attraction featured a controller that could dial in a heading (Visible Bottom Right), that could be followed with this Left / Right Turn Indicator.   This made it far easier to hold a heading over long periods, particularly when fatigued.  It used a Wind-Driven Generator to create an induction field. The Anemometer or Windmeter that produced this electrical output was located above the fuselage just behind the wing. This 3 piece system fell out of favor by the mid-1930s.

Markings I believe these are recorded markings for Fuel consumption from the different Fuel Tanks to keep the plane balanced. Hard to read the markings, but one looks like 'RW' and next to it, 'LW' -- perhaps left and right wing tanks.  I see 4 columns of marks. There were 5 fuel tanks, with 3 tanks in the wings and 2 in the fuselage for 450 gallons of fuel.

Inclinometer  In 1927 Charles Lindbergh chose the lightweight Rieker P-1057 Degree Inclinometer to give him climb and descent angle information.    It was a T-shaped pair of tubes instrument with luminous yellow-green fluid. The upper tube (slip or roll indicator) provides ±10º range, the lower tube (angle of attack or pitch indicator) provides ±30º range.

Periscope Lindberg decided to build the cockpit behind the fuel tank, so that he would not be sitting between the engine and the fuel tank in case there was an accident.  On the other hand, building the cockpit behind the fuel tank made visibility much more difficult. To avoid this problem, he installed a Periscope which unfolded on the left part of the airplane.  Next to it is the Horizontal Lever that folds it In or Out.
Fuel Selectors Quite obviously, Fuel Management was a big deal for this flight, hence the cluster of these fuel valves, used to control the flow of fuel from tank to tank.   If you look at the upper right of the control panel you'll see some markings that Lindberg used for his Fuel Management.
