AI Item Analysis

·AI can make mistakes·Verify before acting
This is a vintage electric mantel clock produced by the United Clock Corporation of Brooklyn, New York, likely dating from the 1940s to 1950s. The clock features a detailed figural scene of a cowboy riding a bucking horse, rendered in a Western theme style popularly known as 'Cowboyiana.' The piece is constructed from cast white metal (spelter) with a multi-toned finish. The rider and horse are finished in a copper-toned or bronze-toned wash, while the base and surrounding gear-like scrollwork appear in a darker gunmetal or black patina. The clock face is integrated into the lower center of the horse's flank, featuring a round dial with Arabic numerals and a rope-style border. The base is rectangular with a textured, rocky appearance and a rope-border rim. Notable features include the dynamic pose of the horse and rider, which was meant to represent the spirit of the Wild West. Regarding condition, there is visible wear to the metallic finishes, particularly along the edges and high points of the cowboy's figure and the horse's tail, suggesting loss of the original plating. The electrical cord is visible and appears aged, requiring safety inspection before use. The craftsmanship is typical of mass-produced mid-century decorative Americana, focusing on expressive form and accessible materials.

AI Appraisal Report

·AI can make mistakes·Verify before acting
Based on my visual examination of this United Clock Corp. 'Bucking Broncho' mantel clock, I have determined it to be an authentic example of mid-century Western Americana, specifically their Model No. 320. The casting displays the characteristic dynamism associated with Brooklyn's United Clock Corp. production from the late 1940s. The condition is fair to good; while the spelter casting remains intact with no visible fractures, there is significant thinning of the copper/bronze wash on high-friction areas such as the rider’s hat and the horse's flank. The original cloth-covered or early plastic cord shows signs of degradation, which is a common liability for these pieces and generally necessitates professional rewiring to meet modern safety standards. The market for 'Cowboyiana' remains steady among niche collectors, though values have plateaued as the primary demographic for this aesthetic shifts. Similar units in pristine, working condition can reach $250, while the wear and untested electrical components of this item place it in the mid-range. Be advised that this appraisal is based on photographic evidence only. A physical inspection is required to confirm if the internal synchronous motor is functional and to check for hidden pot-metal fatigue (zinc pest) inside the casting. Full authentication would involve removing the rear casing to verify the internal United Clock Corp. stampings and ensuring the gear-train hasn't been replaced with a modern quartz movement, which would significantly decrease the horological value.
