First two photos are of a Weaver dual can motored RS-3 I painted about 8 years ago. This scheme (orange hoods, black cab, and no letering aside from the NH emblem and unit numbers) was applied to about half of the New Haven's RS-3 fleet in the early 60's, as they came back from a rebuilding at Alco (plus 2 additional units the New Haven rebuilt in-house).
Next two photos were taken yesterday - in the process of painting a Weaver universal drive RS-3 into the pullman green/orange paint scheme used on the New Haven's first batch of RS-3s (much like Melgar's 531 in the post above). The second batch arrived with the hood tops also painted pullman green. Adding a more detail on this one than I did on 529 - I sanded off the molded-on grab irons and added brass ones on the shell, replaced the molded-in fan grill on the hood top with brass one, and added brass handrails on the frame.
