This is an unusual light bulb socket extension with both a male and female end. The standard bulb socket has a turn key and the socket appears to be brass clad over a porcelain body. I believe this style socket is often referred to as a Fat Boy. The brown Bakelite switch is a flat turn key style that is marked with an F. I have not been able to establish what company the F stands for. The brass is marked; 250W - 250V and there is also an F within a circle. It takes a standard base light bulb. The other end of the old cloth cord has a male end to screw into a light socket. It has a porcelain core and the back of the housing is made of brown Bakelite. This end screws into a standard base socket.
It measures between 6 ½ and 7 feet in length and works as shown in the photos. This has not been disassemble, refurbished or cleaned. It is in original, as-is condition. The cord is dingy and dirty appearing but does not seem to be broken. The end into the socket is wrapped with old tape and was probably cloth frayed. Although this is in working condition it should be considered as an old vintage piece and it is not guaranteed for safe or prolonged use as is.
