I am always a little curious when someone is questioning another person about something, and the answer is "Just because it was always done that way".
We have much more information about these early cards than Burdick had available to him. If we can show that Burdick was wrong, then maybe his info should be corrected. I'm not sure how to go about updating the ACC, but there should be a way to make it happen. I'm sure there are other mistakes that Burdick made, and there are also inconsistencies with the set designations. I posted this is another thread:
Since I collect Coupons, I have always wondered why the Coupons are listed as 1910-1919, Types 1, 2, and 3. Using that logic, shouldn't Goudey's be listed as 1933 through 1941 Types 1, 2, etc.? Playball 1939-1941 Types 1, 2, and 3?
Burdick isn't the only one who has some errors in their information. If you look at Lew Lipset's Encyclopedia and carefully look at the New Orleans cards, you will see some minor errors.
The designation of the T213-1's really doesn't matter, but it is fun, and interesting to read other peoples opinions.
