Using this ALCO model is easy. Just connect it to an analog DC power source and watch it run. When handling, be gentle as it's a fragile brass model. To maintain it, keep it in a dry place to prevent further tarnishing. If you notice any excessive noise or issues with the motor, check the connections first. When storing, use the ReBoxx foam insert and the original box to protect it. Remember, don't use personal checks or cash by mail for payment.
