I have done some research about this topic. I took a different approach to putting T206s onto the same "sheet" though. In no way would I call my conclusion "definitive", but the visual facts are hard to deny.
Instead of using miscut T206s, I went about it using wet sheet transfer evidence that appears consistantly on 12 T206 player's cards. For instance, I have found close to a dozen McGraw (glove at hip) T206s that all display the same transfer. Also, if Teetwoohsix purchased the group of T206s that 3-2-Count had up for sale recently on the BST, then he has one of the players from this grouping.....Hummel.
Over the last 3 years, I have gathered a large inventory of scans with T206s displaying various oddities and errors. After looking at the 2 scans that you have provided of Oldring & White, I see now that these 2 T206s have been graded. I have scans of them when they were raw.
Miscut backs seem to appear in just about every different back brand. If it were my choice, I would focus more on the rarer backs towards building a sheet, because the Piedmont and Sweet Caporal miscuts appear more often.
Hope I've answered your question or helped in some way. If I can provide any more help, let me know.

The Piedmont miscut has Bowerman on the front.
