Were these PRR versions ever made by K-Line? I've only ever seen them in catalogs and my collector's guide only goes to 1998. They are the 13 1/2 inch cars. The only PRR ones I've seen are the FOM and Liberty Ltd. What's interesting is the observation car is a totally different design than the others I've seen.
