Santa Fe FP-45s

Does anybody know what number series the Santa Fe’s FP-45s were when they were in passenger service in the '60s? The current Athearn models are numbered 5941, but I think that was from when they were renumbered into the freight series of F-45s.

Thanks, Don! Weren’t they subsequently renumbered into the 90-class with the arrival of the Super Fleet Dash 8-40Bs?

When received in late 1967 they were 100-108 they were renumbered late 1969-1970 overall renumbering to 5940-5948. Then they were renumbered to 5990-5998. Then when the warbonnet was brought back they were renumbered 100-108 again.
