Hello All,I am looking for the best resource (book/website) on Pullman cars operated by the PRR from the late 30's through 1945, preferably with images of the cars. I have been looking around online and it would seem some of the websites that had this info are now down or no longer function.I am also looking for the most authentic cars for this period and it looks like Branchline is best in that regard, minus the fact you have to upgrade the trucks for the cars to run well. If anybody has thoughts on companies that make authentic pullman cars for this period I would be happy to hear your thoughts.Thank you!
