Other than Milwaukee Road, I also prefer tinplate without specific road names. To this end I purchased the red/black/gray/golden yellow Proto 2 "Circus" version of the 400e. It arrived with the incorrect CNJ brass plates installed, which I didn't want, so I asked MTH to send me the correct "Circus" plates, which they did.
If I were you I'd buy a shiny all black version of the 400e without a road name.
