I did this quickly, so if I made a mistake, cut me a bit of slack.

I used the following scarcity rating for the backs from Scot Reader

1. Brown Lenox
2. Broad Leaf 460
3. Drum
4. Uzit
5. Red Hindu
6. Black Lenox
7. Broad Leaf 350
8. Carolina Brights
9. Piedmont 460/42
10. American Beauty 350 No Frame
11. American Beauty 460
12. Cycle 460
13. Brown Hindu
14. American Beauty 350 Frame
15. Sovereign 350 Apple Green
16. Sovereign 460
17. Cycle 350
18. Sovereign 150
19. Tolstoi
20. El Principe de Gales
21. Sweet Caporal 460/25
22. Sovereign 350 Forest Green
23. Old Mill
24. Old Mill Southern
25. Polar Bear


If you start at Brown Lenox and move down, eliminating cards till you get to the end, the most "common" back you need is Polar Bear for Demmitt and O'Hara STL variations, and then it is Old Mill SL for those printed without Hindu Brown backs, and then an Old Mill BBS. As most would guess, it belongs to Elberfeld Washington Portrait, which was printed only with Piedmont 350, SC 350/30, SC 350/25 and Old Mill Backs.

Here is the full rundown:
