Not sure what you mean by "older." I assume you mean model sleepers, as in HO, etc. Assuming this, don't know a lot about older passenger cars produced years ago. If you mean Pullman type passenger/sleeper cars, there's not a lot produced currently-mainly Con-Cor/IHC--not high on quality (particular truck/weight issues and not prototypical). I think many of us have been waiting for the Walthers series to come out in Frisco logo which would be a significant step-up from IHC--don't know if Walthers will ever produce these in Frisco, though. If this isn't the area you were after, please feel free to specify more. Jim
