Top writers in the HO field

I saw this list shoved down in the bottom right-hand corner of the April '52 issue of Model Trains. I assume it was an advertisement of some sort - weakly disguised as content - regarding the writers that Model Trains featured. Regardless, it's an interesting list of names of writers and modellers from that early post WWII era. Some I recognize, some I don't and should look into. No E. L. Moore yet as he didn't publish anything until 1955, although two of his friends, Bart Crosby and Bill Rau, are there.
