I do have prewar flyer, most especially the streamliners. No one carried these into the postwar era. Lionel, Hoge, AF, etc. The only problem I have is the reversing, and specifically auto reverse. Because of their little
legal dispute with Lionel, Af came up with some creative auto reversing. I think on any given day Af
was right up there with Lionel in the prewar era. And a lot of times better.
