These tanks are shortened versions of the diesel fuel tanks ACF built for the CB&Q and GN in the mid '60s. In other words, Athearn's "62-foot tank car". The tank barrel might be a tad slimmer.
I couldn't find a GA drawing for them in my ca-1970 GA book. Something else to look for in the archives. Couldn't make it this week. Hope to be there next month.
