This HO scale brass lounge observation car is a great addition to your model collection. To use it, simply place it on your model train track. Since it has no lighting or interior details, you can customize it according to your preference. When handling the car, be gentle as it's a fragile brass model. Store it in a dry and clean place to prevent further tarnishing. If you want to clean it, use a soft cloth. Remember, it's missing one small detail part from the underframe, so be careful not to lose any other parts. Also, keep in mind the shipping and payment terms when you make a purchase. If you're not satisfied, you can return it within 30 days, but you'll be responsible for return shipping unless it arrives damaged.
