Hankscraft type electric motor, as used in many model railway point (turnout) controls, as stall type. Draws very little current at stall, so doesn't need limit switches or other control circuitry. Fitted in plastic case, original use as shop window display, with plastic gears to move an arm backwards and forwards. Can of course be used for original purpose, as moving window display, or use the motor and gears for any other purpose. Very hard to get now, more than 12 available. $6 each plus pos
