ADCO stood for Acoustics Development Corporation—a company specializing in metal telephone booths, enclosures, directory signs, and shelves, all designed with acoustic performance in mind They held a trademark for “ADCO ENCLOSURES”—defined specifically to cover metal telephone booths, public equipment kiosks, and ATM booths The brand name “A ADCO” was filed in 1962 and registered to Acoustics Development Corporation, describing acoustical telephone booths and panels What Did They Make? Beyond catalog images, several sources mention product types: An ADCO Model 120 booth was listed for sale, measuring approximately 32″ × 27″ × 85″ and weighing around 205 lb, giving us a practical size reference ADCO collaboratively provided replacement enclosures—like Myrmidon’s MC-101—as modern equivalents for ADCO’s Model 10S and Model 16 booth types There are also vintage ADCO-branded illuminated signs (e.g., for Ohio Bell) used with phone booths, showcasing their branding and aesthetic style In Summary ADCO (Acoustics Development Corporation) produced durable, acoustically designed metal phone booth enclosures throughout the 1960s–1980s.
