This HO brass Southern Pacific Dynamometer Car is a great addition to your collection. Since it doesn't have lighting, there's no need to worry about electrical issues. When handling it, be gentle because it's a fragile brass model. To maintain its appearance, you can use a soft cloth to gently wipe off dust. Avoid using harsh chemicals as they may damage the moderate tarnish on the unpainted surface. When shipping, the item is packed very well, but still check it carefully upon arrival. If you're not satisfied with your purchase, you can return it within 30 days, just make sure to follow the return policy regarding shipping costs.
