Development of the Münzfernsprecher 28
| The Münzfernsprecher MF 28 was introduced from 1928 as a coin-operated public telephone developed for the Deutsche Reichspost. It was manufactured in Berlin by E. Zwietusch & Co. Telephon-Apparate-Fabrik, continuing the evolution of standardised German payphone systems during the interwar period. Technically, the MF 28 was an electromechanical wall-mounted unit combining a dial telephone with an integrated coin mechanism. It was designed for reliable operation in public environments, with internal systems regulating coin validation, call initiation, and duration. The model supported a range of call types, including local calls, operator-assisted services, and long-distance connections, reflecting its role within a structured national network. After the Second World War, the MF 28 continued in service, particularly in East Germany under the Deutsche Post. Many units were refurbished, including repainting and modification to accept different coin types, extending their operational life well into the late 20th century. Remarkably, these telephones remained in use even after German reunification. The Münzfernsprecher 28 illustrates the durability and adaptability of German payphone design, serving across multiple political eras while maintaining its core electromechanical functionality. |
