J, the cars made in 2005 are "correct" (quotes because they are not copies of the actual cars) for the 1937 Daylights which were all corrugated and also lettered in the pre 1946 scheme of "Southern Pacific Lines". The Shasta didn't begin service until after 1946 so "Lines" was correctly omitted. I think smooth side cars actually began service in the early 40s on various trains.
I was adding GGD to Lionel as the only 3 rail manufacturers offering more correct diaphrams. Now to figure out a way to paint them to match the car sides.
I have started lobbying Scott to rerelease the Daylight cars in both early and late lettering schemes. Hopefully those planning to get the Lionel and MTH Daylights will do the same.
