Both Ron Nixon and Warren McGee photographed the 103 in freight and passenger service on the NP in 1940. Seventeen of their photos are available on line in the Ron Nixon collection of the Museum of the Rockies. The second photo that you posted was taken by Ron Nixon in Missoula, MT on March 6, 1940. Note that the NP's dynamometer car is behind the 103.
