Converter, E27 to 2 x socket
In the 1930 – 1940’s it was common that there were no sockets in rooms in simple houses or farms. Only a modest lamp or just a bulb in a socket would be hanging from the ceiling. For those circumstances, the agent would find in his dropping container a converter like this one, to screw in the lamp socket, the bulb in the converter again and obtain 2 additional sockets.
