I will try to post some pics and explain my process for using the original motors in the Gilbert turnouts.
The light shutter is removed and the coil is removed and installed on the bottom side of its base.
I marked the position of the of the plunger lock on the plunger plate, before taking it off to bend the plunger plate, so I could reinstall in the original position.
When the turnout is reassembled it operates as the original turnout did, but now the motor is under the turnout and out of sight. Of course you need now to cut a hole in the layout to clear for the motor.
