It's my understanding that Colgan's printed e254s from 1909-1911, and that Autosales did not get involved until e270. All of the square Colgans seem to correspond to the 1909 e254. I can't explain the absence of Atlanta Crackers, but maybe the reason there are no other Southern Association/Southern League square Colgans (except Memphis as you noted) is because there were no corresponding 1909 e254s for those players. It appears the Birmingham and Chatt players would have been printed after 1909, and while the two Nashville players were there in '09, they were also there in 1910---maybe their e254s were not issued until then. I'm just going on some research from Baseballreference.com tonight, so if you have better info, then I'll gladly defer.
