Not the smartest guy on the topic, but here's what I know:
American Flyer "Wide Gauge" was built to similar size as Lionel
"Standard Gauge", both of which were larger than "0" gauge and smaller
than LGB. lionel had copyrighted the term "Standard Gauge" for toy
trains so Flyer couldn't use it, even though the two products(plus those
of IVES, Dorfan, and Boucher) were the same size and could be run on the
Standard/Wide Gauge was primarily a prewar product; the lines apparently
disappeared during WWII, but there has been a revival of sorts due to
your above mentioned McCoy company, RichArt, new Lionel, and Mike's Trin
Hope this helps.
