The photographer asked wiki contributor Johannes Maximilian for information about this vehicle and is grateful for the information provided:
The lorry is probably a Mercedes-Benz L 311 or L 312, built from 1949-1961, has a 4.58 litre, straight-six, precombustion chamber engine, producing either 90 (before 1956) or 100 PS (1956 and later). This lorry was very common in Germany and known as the 90er-Mercedes. Pre-1955 models were named after their payload, respectively L 4500 (L 312) or L 3250 / L 3500 (L 311). This one looks like a "special model": it has a split windscreen and a double cab. As far as I know, these were made by third-party manufacturers. The combination of a double cab and split windscreen often indicates that the vehicle was originally used as a fire engine.
