Art M.Hi Ted,
Of the 5 T206 cards you have not confirmed with Piedmont factory 42 backs in the 350/460 series I have seen 0 of those remaining 5.
In the 460 only series I have seen these with Piedmont factory 42:
Merkle, throwing
Seymour, portrait
Wiltse, portrait with cap (I own this one)
My Piedmont survey is a bit behind but the data is accurate.
Regards,
Art
