Has Lionel, MTH, etc. produced a streamlined passenger car with smooth sides and fluted roof? I am going to paint an NP North Coast Ltd. (light green/dark green seperated by white stripe) train using Lionel F3s (with moderate detailing) and have Lionel smooth sided/smooth roof and fluted side/fluted roof cars to choose from. Problem is, NP used smooth sided/fluted roofs for their NCL. I am not a rivet counter but I would consider purchasing five or six cars of the smooth sided/fluted roof variety for this project if they are available. Thanks in advance for all assistance.
