Vintage McGraw-Edison Bersted Zero Electric Desk Fan

This is a mid-century electric desk fan, specifically identified as a 'Zero' model produced by Bersted Manufacturing Division of McGraw-Edison. The item features a heavy cast-metal base and motor housing finished in a classic industrial battleship grey or hammertone blue-grey paint. It possesses a characteristic four-blade design, with the blades appearing to be made of aluminum or a similar lightweight metal that shows significant oxidation, surface pitting, and age-related darkening. The protective cage is constructed from bright finished wire (likely chrome or nickel-plated steel), showing some minor surface rust and loss of luster. A distinctive red and gold center medallion on the cage face displays the 'ZERO' branding in bold black lettering. The fan is mounted on a tilting neck, allowing for vertical adjustment, secured by a large slotted screw. The condition is fair to good for its age, estimated to be from the 1940s to early 1960s. There is visible wear to the painted base, including scuffs and small chips. The power cord is a black two-prong variety that appears to be a later replacement or in relatively preserved condition, though electrical safety should be verified. The overall craftsmanship is typical of the sturdy, utilitarian consumer appliances of the American post-war era.
