Yes, I've already looked at that. The "City" and "Star" versions look nothing alike, as far as windows go. And. last time I looked, Brass Car Sides didn't have a "Star" set either.
I got lucky with a CB&Q coach. I saw the "Silver Larch" in Pasco, in both CB&Q and Amtrak lettering, and Kato's car worked for that. It started out as a sleeper, but when the CB&Q rebuilt it, they didn't change the windows!
