This video from oorail.com looks at the Bachmann pack of 3 weathered conflat wagons with AF containers in light blue. Each AF container is separately weathered. The conflat wagons are of very high quality, medium weathering with small tension lock couplings. The conflats are large enough to support two AF containers each but usually they were seen with one in the center. The Bachmann product code is 37-981 and as of August 2014, the product is still available. This particular model is suitable for layouts based between 1963 and the early 1970s.
