Anyone modeling the Santa Fe rebuilds should at least try and find a copy of Santa Fe Railway Rolling Stock Reference Series, Volume 2, Refrigerator Cars, by C. Keith Jordan et al. I have used this book as a reference to build a creditable fleet from both CB&T and IMR kits. I would suggest building at least one IMR kit first, then use it as a reference to superdetail the CB&T kits. These kits do get a bad rap from some, but I've found that, with a little bit of TLC (and a LOT of patience) they will build into a fine looking car. The book is available in digital form from the ATSF Modelers Society. I was lucky enough to find a hard copy on E-bay, but good luck with that! (^O^)
