As the name implies, "Brass Car Sides" sells, well, "brass car sides". Said sides are designed to be mounted to pre-existing passenger car bodies (either American Ltd passenger car "core" kits, or mass-manufactured cars from the likes of Kato, Con-Cor and Bachmann). BSC's catalog is extensive, covering literally dozens of different roads and car styles. And no, I'm not going to try to cover them all here. If you're interested, I suggest visiting their website - Brass Car Sides
