ANTIQUE 1920s Oxweld Model A Carbide Railroad Lamp GREEN LENS Stamped ID
This is an extraordinarily rare, museum-grade antique Oxweld Railroad Type "Model A" Calcium Carbide Acetylene Gas Inspector Lamp featuring its original, uncracked Signal Green glass lens and an authentic railroad inventory stamp debossed on the back of the handle frame. Manufactured by The Oxweld Railroad Service Company (Chicago, IL), this heavy-duty pre-patent industrial piece is an absolute unicorn for serious railroadiana, tool, and maritime collectors. The lamp utilizes a dual-chamber steel and brass body with a top-mounted water-drip valve and a pristine internal chrome reflector.
The defining features are the thick, deeply convex emerald green glass lens-used historically for specialized yard signaling or switch tracking-and the clear, factory/railroad-stamped inventory serial numbers on the rear metal handle frame. Includes the original heavy steel bail handle with a turned-wood grip and the integrated rear mounting clip.
WHY THIS PIECE COMMANDS A PREMIUM. Ultra-Rare Signal Green Lens: While standard clear-lens Oxweld lamps are common, surviving examples with an authentic, uncracked green glass lens are almost non-existent on the open market. This is a top-tier centerpiece for serious collection displays.
Authentic Railroad Handle Stamp: The custom inventory serial number debossed on the back of the handle verifies its historical field service, transforming it from a general utility piece into an officially issued railroad artifact. Flawless Condition Survivor: Finding a century-old active utility lamp with zero cracks in the glass, pristine metal structural integrity, and zero rotted components is exceptionally rare. Pre-Patent 1920s Production: The top lid features the "Model A" designator without the later 1932 patent stamps, identifying this as a scarcer, highly desired early-production run. Model: Railroad Type Model A (Pre-Patent Stamped). Lens: Authentic Solid Convex Signal Green Glass (No Cracks). Markings: Debossed Railroad Inventory / Serial Stamp on Rear Handle Frame. Materials: Thick-Gauge Steel, Solid Brass, Chrome Reflector, Turned Wood. This lantern is in phenomenal shape. The green glass lens has minimal cracks. The dark industrial steel and brass body shows an incredible, untouched natural patina with zero rust-through holes or structural damage. The carbide chamber threads smoothly, the front door latch snaps securely, and the internal reflector plate remains exceptionally bright and clean. The handle stamp is deep, legible, and crisp. Green signal glass from this era cannot be replaced.
