It appears to me at looking at the eight variations offered by Atlas, none of them have the "W" corner 4/4 Dreadnaught ends. Am I correct? Their #1 is clearly Square corner. Only owners w/the W" corner 4/4 Dreadnaught end were Western Maryland and Missouri-Illinois, 1,000 cars it looks like.
If I do Mike & Ike I will pretend the ends have "W" post, hah
