Paulin Altimeter Value Guide

The Paulin Altimeter is a landmark of early 20th-century precision engineering, serving as a vital aneroid barometer for aviation and surveying between 1920 and 1940. These American-made instruments are highly collectible for their historical role in navigation and their intricate brass and glass construction.

What Is Paulin Altimeter Worth?

The typical price range for Paulin Altimeter is $100 - $110 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• Condition of the leather case, as these often show significant wear from field use in surveying.
• Clarity and integrity of the glass face and the legibility of the altitude increments on the dial.
• Functional accuracy of the needle response to changes in atmospheric pressure.
• Presence of original brass hardware and the overall patina of the metal components.

How to Identify Paulin Altimeter?

• Verify the 'Paulin System' branding on the dial face, typically indicating its USA origin.
• Check for the original protective housing, which should consist of a fitted wood and leather carrying case.
• Inspect the internal mechanism for the characteristic high-sensitivity aneroid bellows used for atmospheric pressure detection.
• Look for the distinct brass bezel and glass cover that protect the precision-calibrated altitude scale.

History of Paulin Altimeter

The Paulin altimeter was a significant instrument for surveying and aviation. Developed in the early 20th century, these highly precise aneroid barometers were used to measure altitude by detecting changes in atmospheric pressure. Their robust design and accuracy made them invaluable for pilots and surveyors before the advent of more modern electronic systems. They are celebrated for their engineering and historical importance in the development of navigation and cartography.
