Using this model is easy. Just connect it to an analog DC power source and watch it run well. When handling it, be gentle as it's a fragile brass model. Since it has some wear on the paint and wheels, avoid rough movements that could cause further damage. For maintenance, you can use a soft cloth to gently clean the body and wheels to keep it looking good. Store it in the original box and foam when not in use to protect it from dust and potential impacts. Remember, it's an older model and harder to find, so take good care of it.
