Dee: Probably not, although there may be an exception somewhere. In Noel Holley's bok on the MILW electrics, I found 16 autoracks in a quick scan of 1973 pictures. Three had screens, 13 didn't, so based on that, they'd probably be rare before 1972 or so. Even in the late 70s there were unscreened racks in service. I will probably buy a few for my 1974 railroad, although I have no place to load or unload them.
