I'm pushing to work on my T206 collecting goal this year (won't make it fully, but want to make good progress), which will feature a different back on each card for the Red Sox players. In my research, it's abundantly clear that not all backs are available on all players, but I'm trying to nail down what backs are available for the players in my search.

In doing so, I'm finding some discrepancies. t206.org has been a great help, including Bill Brown's spreadsheet. In the case of Tris Speaker, the field is blank for having a Tolstoi back, although population reports from the three big TPG total 10 examples. I also enjoyed Mark Peavey's "The Mysteries of T206," including the breakdown of printing series at the end, but it appears that not all backs were printed even if a card was in that printing series. Back to Speaker in this case, who was denoted as only printing in the 350 series, but not a single TPG appears to have graded a Speaker with an EPDG back, which was one of the backs in the 350 series.

I realize that my strategy in pursuing my T206 goals is going to change, but I was wondering if there was a single resource that I've overlooked that would outline which backs are available for each player.

And sorry in advance if this has been addressed in a previous post, I searched for a while without finding one.
