Vintage Chicago Furnace Supply Co. Advertising Tape Measure

This is a vintage pocket tape measure featuring advertising for the Chicago Furnace Supply Co. The item has a distinctive 'archtop' or semi-circular metal housing with a flat base, a design common for early-to-mid 20th-century promotional measuring tools. The case is constructed from polished brass or brass-plated metal with black recessed lettering. The face of the tool is prominently embossed with 'CHICAGO FURNACE SUPPLY CO.' in an arched serif font. Below the central rivet point, it features the slogan 'QUALITY ONLY - SINCE 1901' and technical instructions stating 'ADD 2 INCHES FOR INSIDE MEASURE,' flanked by horizontal arrows. Physically, the item appears to be approximately 2 inches in width at its base. The condition shows moderate age-related wear, including minor surface oxidation, light scratching, and some darkening of the brass patina, particularly near the edges. The tape itself is retracted and secured within the housing. The typography and construction suggest a manufacturing date between the 1930s and 1950s, serving as both a functional tool and a piece of industrial memorabilia from a long-established Illinois-based company. The craftsmanship is robust, characteristic of utility goods from that era meant for professional contractor use.
