Toby - as best I can tell there is no T202 with Devlin and Wiltse on the side panels of the same card. I assume you are referring to the "Too Late for Devlin" mid-panel which shows on 6 cards with the following combinations (sorry, I've got no opinion on if it is Joe Jax):
Ames/Meyers
Crandall/Meyers
Devlin (Giants)/Mathewson
Devlin (Rustlers)/Mathewson
Marquard/Meyers
Meyers/Wiltse
