Vintage Steel Altitude Gauge – Star Brass Mfg. Co. Boston

The Star Brass Mfg. Co. Boston manufactured this vintage steel altitude gauge to measure liquid levels in industrial tanks. It features a steel base with a brass top, creating a durable and functional design. The glass face remains in excellent condition, making the markings and dial easy to read. However, its working condition is unknown, making it best suited for display or collection purposes.

An altitude gauge, also called an altimeter, measures the height of an object above a fixed level, typically sea level. It does this by sensing air pressure and converting it into an altitude reading. As air pressure drops, the gauge registers a higher altitude. While people often associate these instruments with aviation, this model was designed to measure liquid levels using similar pressure-based principles.

Features:

• Steel base and brass top for a strong and lasting build.
• Engraved plate with clear manufacturer details, including:
  • “Star Brass Mfg. Co. Boston” – original branding.
  • “Height of Tank” – indicating measurement levels.
  • “Weight of Oil 7 1/4 lbs. per gal.” – used for calibration.
  • “6 in.” – possibly referring to a measurement parameter.

Well-preserved glass face, ensuring a clear and readable display.

Because of its historical significance, this industrial salvage piece is perfect for collectors, decorators, or anyone interested in vintage measuring instruments. Whether displayed in a home, office, or workshop, it adds a unique touch of history and function.
