Best I can tell is around 1908. Here is a list of the numbers, years they were made and types made during those years.
I can't date it for you, (the date should be on the piece itself) but the machine isn't worth much at all. maybe $25.
1924
the westinghouse free electric sewing machine is $455
Westinghouse Electric and mfg co 110 volts style 281650
1925
This number is the style of the electric motor. The machine serial number is probably on the big flat machine base just below the electric motor

Have you found out anything on your machine? I have the same one and am looking for some answers as well. Thanks!
The difference between an electric sewing machine and a manual sewing machine is only the method of propulsion. The electric machine uses an electric motor, while the manual machine uses a hand crank or foot pump to power it. The actual sewing machine is the same.

An electric sewing machine does it's work by using electricity to move the needle up and down, and rotate the bobbin. The mechanical parts of a manual sewing machine, had to be set in motion by turning a handle, or pedal. An electric sewing machine has an electric motor attached to these rotating parts, by belt or gearing and operated by a foot switch. This makes it less tiring on the arms or feet, you can keep sewing faster and longer.
