Tony, to that end, I've been meaning to ask. For the WP reefers, is there an AFE list or something that reflects which of the 2000 AC&F cars got Bettendorf and which got Built-up? The NPRHS has such a list for the NP Reefers, and it helped me get the right car numbers to match the correct versions.
No, no documentation. I inferred from the dates that about 200 of the WP cars differed from all the others and had Bettendorf, but I have no proof.
