Maybe some of you UP Modelers aut there can give me a hand.
Can someone point me in the right direction to find photos of late GP9's,
specifically , GP9's as delivered in 1957, units UP 300 to UP 349. Cockle's books
and others I think, only deal with the units as they were modified later for
use with the turbines. Drawings show Two air tanks below the sill but any
photo only shows one. "Union Pacific 1977-1980" by George Cockle, on Page #55
shows the drawing as well as a photo of UP 338B dated 10 Sept.1977. Which is
correct as delivered? My StreamLiners only go back to Volume # 11.
If there is some site on the web that has some early shots, I would appreciate
knowing about it, or them, as the case may be.
Thanks for any help,
