Besides the Cal Classic sceneries, there are a lot of others that backdate airports to the 50's and 60's. I install them into Silverwings, also. I have 4 installs right now, plus one pure install. Goldenwings, which has everything up to the end of WWII, Silverwings which has everything from the end of WWII into the early 80's, one named 80's which starts in the late '70s thru around 2000, (this one has my MAIW Top Gun package installed) and one that includes nearly everything else up to the present. Since we have a lot of restored aircraft flying today, I have a lot of early ones also. Each install has different scenery packages, as well as different types.
