Antique Brass Industrial Pressure Gauge

The Star Brass Mfg. Company in Boston likely made this Antique Brass Industrial Pressure Gauge in the 1920s or 1930s. It represents a key piece of American industrial history and includes several patent dates (July 30, 1889; January 5, 1892; and July 4, 1893) along with patent number 248,736 on its face. Its 12-inch diameter shows it was designed for important industrial applications.

The glass covering remains mostly intact, but part of it has broken, as shown in the photos. The pointer is missing, which makes it better suited for display or repurposing. Despite these flaws, collectors will value its solid brass construction, bold markings, and historical details. Industrial décor enthusiasts will also find it appealing for its unique design and history.

Features:

• Brass Construction: Solid brass adds durability and a classic industrial look.
• Historical Details: Patent dates and numbers add authenticity and context.
• Large Size: Its 14.25-inch diameter makes it a strong display piece.
• Boston-Made: Star Brass Mfg. Co. created this gauge, a trusted name in early American industry.

This gauge is a great option for collectors of industrial antiques, fans of steampunk décor, or anyone interested in repurposing vintage items. Although it shows wear, such as the missing glass and pointer, its sturdy build and historical significance ensure it remains a standout piece.
