As promised, here is the updated confirmed back variation list. But first, as a reminder, are the three various backs, shown left to right as Type 1 ('B' of 'BALL' in 2nd line of text underneath 'p' of 'pictures' in the first line), Type 2 (same 'B' under 'i' of 'pictures) and Type 3 (aka Reversed Type 2) (text reads bottom to top on back, and like regular Type 2, the 'B' is under the 'i'):

And here are the updated lists, with new additions in bold (all Type 3), and a new category ("Cards only seen in Type 1"), which surprisingly has a couple of bigger name players that one would figure that all existing backs would have already been identified. Edit to identify that Pat found 4 of the 6 on the list, including the Cobb and Speaker. Because of this I am thinking it likely that the other two will be verified...?
