John, To my knowledge there has never been a Frisco business car imported in brass, I'm sure if this is incorrect someone will be able to correct me. Seems like I do remember a few years ago Overland proposing a run of BN business cars and one of the potential cars was a former Frisco car, bur I think it was to be in BN colors. But I don't think the project ever got off the ground, it would be nice if they were done one of these days. Brad Slone
