Vintage Triplett Model 337-S 0-150 AC Voltmeter Panel Gauge – Square Bakelite Face

• Manufacturer: Triplett Electrical Instrument Co. (Bluffton, Ohio)

• Design & Scale: Calibrated specifically for Alternating Current (A.C. VOLTS). It utilizes a fine black counter-balanced needle pointer indicator with a zero-adjust screw positioned on the lower front section.
• Enclosure: Features a square front bezel measuring approximately 3 inches across, tapering to a rear round barrel enclosure measuring about 2.75 inches in diameter/1.25 Depth.
• Hardware & Markings: The reverse side features two heavy-duty brass threaded terminal connection posts with integrated hex nuts and four corner-mounting threaded stud extensions. The rear casing is clearly stamped with the factory serial code 321326.
• Condition: Pre-Owned / Estate Used. The face remains bright, exceptionally clean, and free of yellowing. The Bakelite housing and rear metal barrel show standard vintage shelf wear and minor storage patina, preserving an excellent industrial look. Sold untried and unpolished, directly as found.

• The Serial Number Dateline: The 321,326 factory stamping on the rear casing corresponds directly to Triplett's mid-World War II manufacturing window.
• The War Production Era: During this specific era (1942–1945), Triplett shifted massive amounts of its factory output in Bluffton, Ohio, to supply ruggedized test meters like the Model 337 series for military radio gear, naval signal panels, and war-effort industrial monitoring machinery.
