I am looking for a few EJ&E flatcars and gons to carry inbound steel loads into a shipyard on my layout set in 1952. Are there any models out there that are dead-on or close-to cars that were in service at the time? I have the Proto 50-ton AAR flat...but was wondering about the green and orange paint scheme. When did that scheme enter service, and what was the prior scheme (black/white, or tuscan/white)? I haven't found decals either...any help is appreciated.
