Hi,
I just came across this Image of the AMERICAN FLYER MINUTEMAN SET - Really a Good Looking Locomotive ! - Pre War - Wide Gauge.
I think that the LIONEL 390E has the most prototypical looking Smokebox Front of the LIONEL Wide Gauge Locos.
I am not considering the Entire Locomotive when saying this.
I am just comparing the Smokebox Front of the various LIONEL Wide Gauge Locos.
There certainly was a lot of different Numbered LIONEL Wide Gauge Locos !
