Large Industrial Gas Cylinder

This is a large, heavy-duty industrial gas cylinder designed for holding compressed or liquefied gases, as observed resting on a concrete shop floor. The physical structure consists of a tall, upright cylindrical metal body constructed from heavy-gauge steel, featuring a domed top shoulder and a flat circular base allowing it to stand vertically. The exterior shows substantial surface wear, featuring extensive rust, pitting, and weathering across the metallic body, consistent with long-term use in an industrial or mechanical workshop environment. At the top center, the cylinder is fitted with a heavy brass valve assembly topped with a light gray painted metal handwheel. Several stamped markings and text are visible directly on the metal shoulder, including faint lettering reading 'ELLIOTT'. Additionally, a prominent warning label is adhered near the shoulder, featuring white text reading 'LIQUEFIED PETROLEUM GAS' alongside a diamond-shaped red and orange warning symbol with the word 'FLAMMABLE'. The identification is based purely on visual observation of the equipment's standard industrial form factor, brass valve fittings, and warning labels, with no specific manufacturer claims verified.

Based on what I can see in the photograph, I have evaluated this large industrial gas cylinder, which bears markings consistent with an 'ELLIOTT' label and a prominent 'LIQUEFIED PETROLEUM GAS' warning label. The physical structure features a heavy-gauge steel body, a brass valve assembly, and significant surface wear including extensive rust and pitting. I cannot verify from a photo the internal integrity, structural safety, or exact manufacturing era of the vessel. Furthermore, any attribution to a specific brand remains a working hypothesis, as markings alone do not provide a guarantee of origin or era. The estimated value range of $50–$150 reflects typical secondary market behavior for used industrial containers of this type, which are often sought after for industrial decor, upcycling, or scrap value rather than functional utility. Condition significantly impacts this estimate; the heavy weathering and rust limit its use strictly to decorative or salvage contexts. To confirm authenticity, manufacturer origin, and regulatory compliance, an in-person physical inspection, evaluation of pressure testing records, and verification of stamping details by a qualified industrial equipment expert would be required. If the cylinder turns out to be a decorative reproduction or lacking the purported brand association, the value would likely be restricted to baseline scrap metal pricing.
