Ok, what I think I know based on the posts. Cudahy Reefers with CRLX reporting marks were owned by the Cudahy Packing company of East Chicago (In 1957). The Sunshine kit 24.17 is for these cars. Also, this means the intro paragraph on page 27 of Gene Green's "Refrigerator Car Color Guide" from Morning Sun is incorrect since he attributes the CRLX reporting marks to Patrick Cudahy of Wisconsin.
Patrick Cudahy reefers were leased from NRC. I didn't see the photo in the NRC section that Dennis mentioned but maybe he was talking about the Billboard Reefer book, which I do not own.
